-// smartany library uses a poor compile time assert. It is actually generating
-// runtime code to call the constructor of the assert class. Most likely to
-// improve performance, the library uses a static instance of the compile time
-// assert object. In theory the code is not thread-safe. In practice, since the
-// compile time assert is an empty class, there should be no problems. The long
-// term solution requires changing smartany to use a better compile time assert
-// which is completely evaluated at compile time and it has no effects
-// whatsoever at runtime. Short term, the code should include these wrappers
-// to silence the compiler warning.
