Compile time deduction of template member function

Is it possible to get the return type of a template member function at compile time?

I guess I need something along the lines of:

template<class T>
struct SomeClass
{  
     // T must have a function foo(int), but do not know the
     // return type, it could be anything
     using RType = ??? T::foo(int) ???; // Is it possible to deduce it here?
}
