I'm not sure it's true. Consider:

        template<class T>
        T foo();

        template<class T>
        void bar();

The value of template parameter is indeed the part of signature.
The return value does not seem to be, since it directly depends
on template parameter, so:

        foo<int>()

quite uniquely specify the type of return value.
