Edit Question
Title
Body
Seen on this site , the code shows macro invocations using a tilde in parentheses: HAS_COMMA(_TRIGGER_PARENTHESIS_ __VA_ARGS__ (~)) // ^^^ What does it mean / do? I suspect it to just be an empty argument, but I'm not sure. Is it maybe specific to C(99) like the __VA_ARGS__ is specific to C99 and existent in C++?
