One fun thing you can do is use .(e,'reply=(foo bar baz)',) if you
want to use some other globbing flags on your data. It's not
applicable for this problem, at least I can't think of a way. I did
suggest it on irc once for sorting an array by the basename:
22:39 <offbyone> I want to sort this by basename so that I order the
elements in this pair of expansions asciibetically regardless of the
directory they're found in.
22:39 <offbyone> (so, for example, if I had A/02_something
B/01_something B/03_something, it'd come out as B/01_something
22:47 <Mikachu> a=( oneglob anotherglob )
22:47 <Mikachu> echo .(e:'reply=($a)':oe,'REPLY=$REPLY:t',)
It would be nice to have a similar mechanism for sorting arrays maybe :).
Oh wait, I just realized it does work, just do this:
% print -l - .(e:'reply=($somelist)':P:-id:)
Obviously, this does qualify in the 'a bit of a hack' category. (And
yes, it does fail if $PWD is chmoded -x, maybe / is a safer bet.)
