well... i used it at least 15 years long without having problems so
we can imagine it's consistent enought :)

should this code be merged in the zsh codebase ? :)

is it a possible open discussion with zsh-workers ? it seems to me i
have a clear idea of how things could work but i have now idea of how to
implement it. maybe i should document it ? (or maybe there are some
archives outthere about why it cannot be obvious?)

in this case i wasn't talking about variables but only function names but
i imagine it goes the same.

once again thanks for your reply.
