transformations of glob results

[Marc Chantreux <khatar@xxxxxxxxx>]

hello people,

i wrote a glob result transformation that way:

    l=( /etc/sympa/*/robot.conf(:h:t) )
    l=( listmaster@$^l )
    print ${(j:,:)l}

but i really would like to know if there is a simple, readable way to
write it in one expression. the perl counterpart would be

    join ','
    , map 'listmaster@'.(split "/")[-2]
    , glob "/etc/*/robot.conf"

and i tried variations around

    print ${(j:,:)${(@)listmaster@${(^) /etc/sympa/*/robot.conf(:h:t) }}}

which

    * doesn't work
    * actually looks ugly

any help from a zsh poweruser ?

regards
