It's not the aesthetics I'm worried about, it's maintainability.  I
had the dubious pleasure of writing most of those special-case parts,
and I'm already beginning to have difficulty remembering what use case
does each one cater to, and how to make sure I don't break it by some
change.  How can we expect others to make changes in such a mess?

I think Stefan suggested a way to achieve this without all this
complexity.  I hope it will be possible.
