--- Comment #3 from Ville Voutilainen <ville.voutilainen at gmail dot com> ---
Looks good so far. I think this is a sufficient start for implementing the
library traits. Does the patch cover template cases as well? Such as

struct B {B();};

template <class T> struct C : T
{
};

SA(__calls_nontrivial_fn(C<B>()));

Anyway, I'll give it a spin.
