Not really, parameter expansion takes place before globbing so you
need to do the * separately before the other stuff. You can cheat and
do things with e:: but that is much slower in this case (and
technically the thing inside the :: is a separate expression too), or
use an anonymous function but all that really does is give you a free
local variable, (eg, () { print ${(j:,:):-listmaster@$^@}} }
/etc/sympa/*/robot.conf(:h:t) (not tested, may have typos) )
