------- Comment #4 from jason at gcc dot gnu dot org 2009-11-21 22:08 ------- Actually, the decltype variant isn't a SFINAE issue either; SFINAE only applies to function templates because it's part of deduction. For a simpler example:
template <class T> struct A { void f (T::type); }; A<int> a; This is ill-formed, we don't discard f from A<int>. -- jason at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|ASSIGNED |RESOLVED Resolution| |INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42132
