Oh yes. I thought about that a lot when I was working on
zle_tricky. It would be nice to turn that completion code into a
general `produce a list of what we need here'-code. The main problem
(I think) is that we would need a good internal representation for
lexed (and parsed) command lines that would be used throughout the
whole code. Once we had this, it wouldn't be too complicated to turn
the completion code (and merge it with the correction code) into the
above mentioned list-generator (we probably would also have to add
some more possibilities for describing command arguments).
