Maybe we should create a new module in the CVS repository, say
slime-extras, for non-essential or not-mature features. That would be
very useful to make such code publicly available. I'm not sure
whether CVS is a good tool for such purposes. Anyway, the core of
Slime should be/become reasonably small and robust.
I'd say the following qualifies as non-essential:
- fuzzy completion
- class/xref browser
- stuff that tries to be to smart
It's not trivial to setup the infrastructure for this purpose. Some
obvious problems are:
1. how and when to load extra code
2. how to write backend specific code
3. how to write documentation
4. what to do when the core changes in fundamental ways
Usually I'd say that it's not worth to bother and we should just drop
the extras entirely, but it's quite tiring to tell every second guy
that SLIME is more than feature complete and that I don't want to add
So, what do other people think of such an approach.
