Well, C libraries implement this as macro rather than function, otherwise you
would be seeing compiler errors if the library is defining an appropriate
function prototype because the macro would be applied to that function
prototype as well!

Where did I say or even imply that?  I said it "requires a C++ compiler"!

I did not say nor imply nor suggest nor in any other way say anything like
that!  To the contrary, I made is explicit that "***legacy*** C support has
been removed".  Even more important, didn't you receive a reply from Nathan
about Object_Struct yesterday that already answered this question...?
