I've also been thinking about similar things.  A lot of the recent
work in zsh has moved more of the intelligence in the code into
the hashtable code.  To use an overused buzz-word, the internals
of zsh have become more `object-oriented' in some sense.  This is
a trend I would like to continue.  The next thing would be to move
some of the command completion and spelling correction code into
hashtable.c.  So (in some sense) each type of object (alias, builtin,
etc...) would know how to complete itself, or spell check itself.
Once this is done, I think we could generalize the code so that both
spelling correction and command completion would be  programmable
in similar ways.

Just a thought.
