/** The `static_assert(true, "")` idiom is commonly employed for
* C++11 or greater to ensure that it is compile-time only
* check that can not be part of the binary file.
* This allows a macro to be used anywhere that a statement
* is expected, and to enforce consistent use of ; after
* a macro. The static_assert is a constexpr that can be used
* in places where raw statements (i.e. 'do{} while(0)') are
* not allowed (i.e. after class member function definitions).
