The top-level declarations are __builtin_va_list (injected by the compiler), Stuff, gThing, and funcy.

Thingy is not a top-level declaration; it's stored within the namespace 'Stuff'. You can iterate through the declarations within a namespace with decls_begin/decls_end; check out the DeclContext class for more information.
