I think it may be confusing a temporary object T1() with a function type -- 
__typeof__ usually handles both. As a wild guess, you can try to do
something like:

template<class T> T make();

typedef __typeof__(make<T1>()+make<T2>()) type;

That means you can handle any custom class (after the registration).  So the
problem is only related to template registration, which makes it a little
easier...
