Cool, I remember wanting this a few times. I just don't remember what
for :). It sort of lets you do array things to globs without assigning
a var first pretty easily, () { print -l /foo/${(U)^@} } Src/*.c

Or arbitrarily nested glob qualifiers, I'm sometimes bothered by not
being able to do foo(xyz)/bar(abc) where xyz would be glob quals to
apply on the foo segment, and abc on bar.

() { () { print -l $^@(e:'REPLY=${(U)REPLY}':) } $^@/*(.) } *(/)
(This is a stupid example, but maybe it gets the point across. :) No
idea why I'm so fond of uppercasing things tonight.)

A heads up, this patch may make zsh crash on startup when reading .zwc
files from before the change. A simple workaround is to either touch
the source file or remove the .zwc files. (Maybe we should bump the
-dev version so this doesn't affect too many people?)
