--// (although not all) pointers.  Therefore, you should use arraysize
--// whenever possible.
--//
--// The expression ARRAYSIZE_UNSAFE(a) is a compile-time constant of type
--// size_t.
--//
--// ARRAYSIZE_UNSAFE catches a few type errors.  If you see a compiler error
--//
--//   "warning: division by zero in ..."
--//
--// when using ARRAYSIZE_UNSAFE, you are (wrongfully) giving it a pointer.
--// You should only use ARRAYSIZE_UNSAFE on statically allocated arrays.
--//
--// The following comments are on the implementation details, and can
--// be ignored by the users.
--//
--// ARRAYSIZE_UNSAFE(arr) works by inspecting sizeof(arr) (the # of bytes in
--// the array) and sizeof(*(arr)) (the # of bytes in one array
--// element).  If the former is divisible by the latter, perhaps arr is
--// indeed an array, in which case the division result is the # of
--// elements in the array.  Otherwise, arr cannot possibly be an array,
--// and we generate a compiler error to prevent the code from
--// compiling.
--//
--// Since the size of bool is implementation-defined, we need to cast
--// !(sizeof(a) & sizeof(*(a))) to size_t in order to ensure the final
--// result has type size_t.
--//
--// This macro is not perfect as it wrongfully accepts certain
--// pointers, namely where the pointer size is divisible by the pointee
--// size.  Since all our code has to go through a 32-bit compiler,
--// where a pointer is 4 bytes, this means all pointers to a type whose
--// size is 3 or greater than 4 will be (righteously) rejected.
--
--#define ARRAYSIZE_UNSAFE(a) \
--  ((sizeof(a) / sizeof(*(a))) / \
--   static_cast<size_t>(!(sizeof(a) % sizeof(*(a)))))

--
--// Use implicit_cast as a safe version of static_cast or const_cast
--// for upcasting in the type hierarchy (i.e. casting a pointer to Foo
--// to a pointer to SuperclassOfFoo or casting a pointer to Foo to
--// a const pointer to Foo).
--// When you use implicit_cast, the compiler checks that the cast is safe.
--// Such explicit implicit_casts are necessary in surprisingly many
--// situations where C++ demands an exact type match instead of an
--// argument type convertable to a target type.
--//
--// The From type can be inferred, so the preferred syntax for using
--// implicit_cast is the same as for static_cast etc.:
--//
--//   implicit_cast<ToType>(expr)
--//
--// implicit_cast would have been part of the C++ standard library,
--// but the proposal was submitted too late.  It will probably make
--// its way into the language in the future.

--
--// The COMPILE_ASSERT macro can be used to verify that a compile time
--// expression is true. For example, you could use it to verify the
--// size of a static array:
--//
--//   COMPILE_ASSERT(ARRAYSIZE_UNSAFE(content_type_names) == CONTENT_NUM_TYPES,
--//                  content_type_names_incorrect_size);
--//
--// or to make sure a struct is smaller than a certain size:
--//
--//   COMPILE_ASSERT(sizeof(foo) < 128, foo_too_large);
--//
--// The second argument to the macro is the name of the variable. If
--// the expression is false, most compilers will issue a warning/error
--// containing the name of the variable.

--  typedef CompileAssert<(bool(expr))> msg[bool(expr) ? 1 : -1]
--
--// Implementation details of COMPILE_ASSERT:
--//
--// - COMPILE_ASSERT works by defining an array type that has -1
--//   elements (and thus is invalid) when the expression is false.
--//
--// - The simpler definition
--//
--//     #define COMPILE_ASSERT(expr, msg) typedef char msg[(expr) ? 1 : -1]
--//
--//   does not work, as gcc supports variable-length arrays whose sizes
--//   are determined at run-time (this is gcc's extension and not part
--//   of the C++ standard).  As a result, gcc fails to reject the
--//   following code with the simple definition:
--//
--//     int foo;
--//     COMPILE_ASSERT(foo, msg); // not supposed to compile as foo is
--//                               // not a compile-time constant.
--//
--// - By using the type CompileAssert<(bool(expr))>, we ensures that
--//   expr is a compile-time constant.  (Template arguments must be
--//   determined at compile-time.)
--//
--// - The outter parentheses in CompileAssert<(bool(expr))> are necessary
--//   to work around a bug in gcc 3.4.4 and 4.0.1.  If we had written
--//
--//     CompileAssert<bool(expr)>
--//
--//   instead, these compilers will refuse to compile
--//
--//     COMPILE_ASSERT(5 > 0, some_message);
--//
--//   (They seem to think the ">" in "5 > 0" marks the end of the
--//   template argument list.)
--//
--// - The array size is (bool(expr) ? 1 : -1), instead of simply
--//
--//     ((expr) ? 1 : -1).
--//
--//   This is to avoid running into a bug in MS VC 7.1, which
--//   causes ((0.0) ? 1 : -1) to incorrectly evaluate to 1.

--//   int i = bit_cast<int32>(f);
--//   // i = 0x40490fdb

--// The classical address-casting method is:
--//
--//   // WRONG
--//   float f = 3.14159265358979;            // WRONG
--//   int i = * reinterpret_cast<int*>(&f);  // WRONG
--//
--// The address-casting method actually produces undefined behavior
--// according to ISO C++ specification section 3.10 -15 -.  Roughly, this
--// section says: if an object in memory has one type, and a program
--// accesses it with a different type, then the result is undefined
--// behavior for most values of "different type".
--//
--// This is true for any cast syntax, either *(int*)&f or
--// *reinterpret_cast<int*>(&f).  And it is particularly true for
--// conversions betweeen integral lvalues and floating-point lvalues.
--//
--// The purpose of 3.10 -15- is to allow optimizing compilers to assume
--// that expressions with different types refer to different memory.  gcc
--// 4.0.1 has an optimizer that takes advantage of this.  So a
--// non-conforming program quietly produces wildly incorrect output.
--//
--// The problem is not the use of reinterpret_cast.  The problem is type
--// punning: holding an object in memory of one type and reading its bits
--// back using a different type.
--//
--// The C++ standard is more subtle and complex than this, but that
--// is the basic idea.
--//
--// Anyways ...
--//
--// bit_cast<> calls memcpy() which is blessed by the standard,
--// especially by the example in section 3.9 .  Also, of course,
--// bit_cast<> wraps up the nasty logic in one place.
--//
--// Fortunately memcpy() is very fast.  In optimized mode, with a
--// constant size, gcc 2.95.3, gcc 4.0.1, and msvc 7.1 produce inline
--// code with the minimal amount of data movement.  On a 32-bit system,
--// memcpy(d,s,4) compiles to one load and one store, and memcpy(d,s,8)
--// compiles to two loads and two stores.
--//
--// I tested this code with gcc 2.95.3, gcc 4.0.1, icc 8.1, and msvc 7.1.
--//
--// WARNING: if Dest or Source is a non-POD type, the result of the memcpy
--// is likely to surprise you.
--
