Using macros to map names to numbers seemed always a little cumbersome
to me. And it does not work in filter files. We discussed this a while
ago (when you said you don't like named variables because they are
inefficient :).

As for code complexity: Sure, the new code makes changes in central
places, which is always dangerous, but I think it is pretty
straightforward, easy to read and to validate.

To be honest, I even thought about moving the existing numbered
variables to the same storage as the named ones (which would reduce code
complexity :), but then it seemed too revolutionary for now...
I doubt anybody would notice a performance hit, though, especially when
we'd use a binary tree.

Quite fair.
