I think, this slightly changes the behavior for existing code. Until now,
AFAIK you can bind a Stmt and a Decl to the same name (e.g. I suspect "match"
might be a name that somebody might have reused). I think it is a good thing to
forbid it! Manuel, do you see any problems with that? We should make a note in
the commit message.
I like the design, but we should leave the final decision to Manuel.

First I thought that these recursive macros are bad, but on second thought, I
kind of like it :-).

It is very important that this list is in sync with the enum declaring NT_*.
Ideally, we would not need both, but if we do, could we put the right next to
each other in the code?
