StaticAssertStdIsSameIntint

StaticAssertStdIsSameIntint is a compile-time assertion that checks if the type `int` is the same as `int`. This is a trivial check, as `int` is always equal to `int`. It is typically used in C++ template metaprogramming to ensure that certain type manipulations or assumptions hold true at compile time.

The primary purpose of such an assertion is to catch potential errors early in the development process. If, in some unusual or future C++ standard, the definition of `int` were to change or be aliased in a way that `std::is_same<int, int>::value` evaluated to false, a `StaticAssertStdIsSameIntint` would fail to compile. This would alert the programmer to an unexpected situation.

This specific assertion is often found within libraries or frameworks that rely on precise type relationships for their internal workings. For example, a library might use `std::is_same` to enable or disable certain code paths based on whether two types are identical. While `StaticAssertStdIsSameIntint` is a redundant check in current C++ standards, its presence can serve as a form of defensive programming or as a placeholder for more complex type checks that might be applied to other types. The `static_assert` keyword in C++ is used to perform these compile-time checks, which are evaluated by the compiler and do not incur any runtime overhead.
