For a function `const int f()`, `decltype(f())` returns `int` on VC++ 11. So some `result_of` tests fail as in #6754. ( https://svn.boost.org/trac/boost/ticket/6754 ) Clang 3.1 and gcc 4.7-4.8 behaves similarly, and this behavior conforms to the C++11 Standard.
I'm confused, because I observe this with VC11 RTM:
const int f() { return 1729; }
int main() { Print<decltype(f())>::print(); }
C:\Temp>meow const int
(I rearranged the code above for readability.) Thanks for pointing this out, Stephan. It's highly possible that I did a wrong test. (I usually use cvref-preserving type-name printer. But, when I used VC++ 11, I think I used typeid + name() for getting the type-name.) So, "For a function `const int f()`, `decltype(f())` returns `int` on VC++ 11." is wrong. VC++11 implements N3276 decltype, but not FDIS decltype. Sorry for the confusion. Regards, Michel
