Hmm, but don't we want it to affect all components? For example, consider
something like:
@interface I
@end
template <class T> class C {};
void f();
void g() {
try {
f();
} catch (C<I> *) {
}
}
I would say that we want the RTTI for `C<I> *` to have the discriminator for
`I`. It turns out my current patch doesn't actually do that; I guess there's a
sub-mangler being constructed somewhere that's not inheriting the RTTI-ness. Or
did you mean something else?
