    How about this?:

function shuffle () {

    emulate -L zsh 
    
    setopt nullglob globdots rcexpandparam
    
    RANDOM=`date +%s`
    [[ $# -eq 0 ]] && set '*'

    reply=()
    reply=($*)
    reply=($reply(e:'REPLY="${(l.5..0.)RANDOM} $REPLY"':))
    reply=(${(o)reply})
    reply=(${reply/#????? /})

    print -l $reply

    return 0
}

    It does the globbing outside, and shuffles correctly. Any way of
making the 'reply' assignments shorter? Should I go definitely for a
'for' loop and an associative array?

    Thanks a lot :)
