Ah, I see. Yes, that sounds reasonable.

Indeed.

I've been thinking some more... maybe we should only use it for
logical grouping. E.g. the parameters from zle ($BUFFER etc.) should
be $.zle.buffer etc. and the ones from the zleparameter module should
use the same prefix ($.zle.keymaps seems to make a lot more sense to
me than $.zleparam.keymaps or even $.zleparameter.keymap). And then
the parameter module could probably use `$.zsh.' as the prefix.

I think the result would be that the names say what they give access
to instead of saying where they come from - and I hope user's will
find this much less confusing.

Then there is the question how far we want to go. E.g. should we
change $BUFFER and friends? The special completion parameters like
$.comp.state, $.comp.prefix and so on?
