-/**
- * @fileoverview Utilities to check the preconditions, postconditions and
- * invariants runtime.
- *
- * Methods in this package should be given special treatment by the compiler
- * for type-inference. For example, <code>goog.asserts.assert(foo)</code>
- * will restrict <code>foo</code> to a truthy value.
- *
- * The compiler has an option to disable asserts. So code like:
- * <code>
- * var x = goog.asserts.assert(foo()); goog.asserts.assert(bar());
- * </code>
- * will be transformed into:
- * <code>
- * var x = foo();
- * </code>
- * The compiler will leave in foo() (because its return value is used),
- * but it will remove bar() because it assumes it does not have side-effects.
