And also because:
# touch /bin/ls'
fail'
% print -- -f\ ${(f)^"$(print -l /bin/ls*)"}
-f /bin/ls
-f /bin/ls
-f fail
-f /bin/lsmod

$() is almost impossible to get right wrt quoting.
print -l -- -f\ ${(0)^"$(printf '%s\0' /bin/ls*)"} probably works a
bit better, but of course it's still useless since the -f is not a
separate parameter.

As an aside, is "$(echo a b c)" the only way to get an 'inline' array
in a ${} expression? I sometimes want to use a glob qualifier on a
middle part of a path but then I need to use temp arrays (and I'd
rather not use $() there).
