[type_traits] is_function
Assuming a compiler supports is_function, will this metafunction check for the presence of member functions in a class? For example: struct Foo { void bar(); }; struct Baz { }; Given the right template argument, will is_function detect the bar() function in Foo but return false_ for Baz? If so, what is the right template argument? If not, are there any known workarounds? Cromwell D.

I think it will return false for both. Maybe "is_member_function_pointer" would be more useful for you? - -- Frank -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFF5evU5vihyNWuA4URAs6eAKDoO/wV9Vb+fUuNw07AMN6vbZvl+wCg30R0 BrmuZN6Nv4lwV9hVohsJvl8= =Wu0v -----END PGP SIGNATURE-----

is_member_function_pointer will not compile if bar is not a member of Baz. However, if I can find a way to detect whether bar is a member of Baz, then I can use is_member_function_pointer in conjunction with BOOST_TYPEOF. The question now is, does such a method exist?
