Checking the Existence of a C++ Class Member at Compile Time


	// A compile-time method for checking the existence of a class member
	// @see https://general-purpose.io/2017/03/10/checking-the-existence-of-a-cpp-class-member-at-compile-time/

	// This code uses "decltype" which, according to http://en.cppreference.com/w/cpp/compiler_support
	// should be supported by Clang 2.9+, GCC 4.3+ and MSVC 2010+ (if you have an older compiler, please upgrade :)
	// As of "constexpr", if not supported by your compiler, you could try "const"
	// or use the value as an inner enum value e.g. enum { value = ... }

	// check "test_has_member.cpp" for a usage example
