For starter, we don't want another debate "python vs ruby vs lua vs
..." as the scripting language :) (for the record I vote Scheme! maybe
with infix syntax)

Seriously though, for things that are evaluated in the background
every single time a command is executed and things that come from many
different places (/etc, $HOME, $XDG, $GIT_DIR) I think absolute
flexibility just makes it harder to pinpoint when things go wrong.
Combination in this case would be a bad thing, not a good one. By
judging case by case before introducing a new condition type, we
probably can see what sort of combination would be and whether we
could accept that.
