--- Comment #13 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-04-12 12:44:13 UTC --- Are any of the examples in this PR actually valid? I think G++ is correct to reject them. foo ::operator+ is parsed the same as foo::operator+ so still finds the member function, the parentheses prevent that.
