It does indeed. Thanks a lot! :-)

That explains what I saw in the debugger - the address seems to be OK
(i.e. the same Sema put in the list) before the cast. But the whole
casting stuff Clang does is a little over my head for now. I'm quite new
to C++ anyway and even the iterators are something I have to get used to.

Thanks for the hint, but I do need to iterate over all attributes and
just give the annotations a little extra treat.
