That's a good point. I have a horrible feeling you mentioned that before
sometime. It made me wonder though: surely PATH is similar. I've always
tended to add to the path in my .zshrc so this makes me wonder if it
wise to set it fully and in .zshenv for similar security reasons.

Yes, or in the same way as how $fpath is set. I've used things like
${fpath[(r)*Core]:-$fpath[(r)*/functions]} in a few places (such as my
zrecompile script) to get at this directory so it might be useful

I did a bit of thinking last week and as for the whole suggestion about
setting $fpath, I think you've convinced me that the current situation
is probably just as good/bad as my suggestion. I think it would
definitely be worse if we ended up supporting both ways of doing it with
a configure option so I won't mention it again. So I suggest we leave it
as it is and I shut up.

I couldn't see it in the docs but these things aren't so easy to find.
If it gets asked much, we can always add it to the FAQ.

As for sourcing compinit, I suppose it might have a performance
implication. I just felt that sourcing is more natural for what it is
doing and is possibly an easier concept for new users to understand.

compinit does its stuff. I'm not too keen on us complicating compinit so
that sourcing it is an option but with autoload being the method
mentioned in the manual.

Sorry, I didn't really know what proto was but assumed it was something
more general and so more useful.

fair enough. Again I've never used it and just glanced to see what it

Er? I saw the ? and meant my comment as an answer but probably got the
tone of it wrong.

In some ways, I wonder that #autoload as a wider feature might be

That's not a bad idea. They'd be out of the way in the Compctl directory
so I don't think it would be too much of an encouragement. More
functions in Compctl would better justify its existence. I've also been
convinced that compctl still serves a purpose.

I would definitely agree with that.
