Returning to this after a bit of a detour through [[ ... ]] expression
parsing:

You could define (via zmodload) an operator that applies filename
generation to its argument, but changes to the internals of globbing
would be needed to make a short-circuit happen.  Then those changes
would have to be exposed somehow so that the operator could use them.

As I mentioned before, in the case of the match failing this would be
exactly as expensive as not short-circuiting.
