This is where the @property keyword makes a difference:

     @property auto ref func(int i)() { return this; }

Now U().func!0 will be a call in your expression. But @property is not 
recommended (deprecated?).

But I think std.traits.ReturnType is more explicit and does work in this 

         import std.traits;
         alias type = ReturnType!(U().func!0);
