[cfe-dev] Determining whether Container<T>()==Container<T>() can compile?

Code such as
std::vector<A> veca, vecb;
veca == vecb;
can only compile if A()==A() can compile, if you'll forgive me taking some
I tried writing a template to determine if a type can be equality-compared
for the purpose of type-erasure:
Adding auto and trailing return type seems to be helpful:
Would the suggestion from Olivier Goffart be something that could be applied
to libcxx to make it possible to write such a template for its stl container
Does anyone else have any other ideas for something that would work with
todays stl implementations?
