  Reminds me of docs/apibuild.py , that's code I wrote like 10 years
ago for libxml2, and I certainly don't remember all the subtelties,
it's certainly not very nice code, but being a generator and automated
parser the good point is that I don't have to remember it, and very
seldomly hack it. I think there is no shame to having "imperfect" code
which does this kind of things as long as it's done in a generic enought
way that you don't have to tweak it often.
  If the extra indirections don't cost anything (except extra code) then
maybe it's fine keeping. I would say the main driver to clean such code
would be if you feel others need to hack on it and it need to be cleaner
and easier to understand.
