Re: [boost] Is there any interest in a casting library where you don't need to specify a type of receiver?

You've found that workaround. :-)
Yes, gcc requires a named return value.

Well, my library contains function adaptors.
While adapting, here's what happens internally:

template<class X>
X const & pass_through_some_adaptor(X const & x) { return x; }

D & d = pass_through_some_adaptor(polymorphic_down::ref(b)); // doesn't compile on gcc.

Therefore, I gave up.
Your library might not be affected, though.
