} Hmm, I like this. For bigger arrays one would have to use `01' and so
} on, but this should be acceptible.

Somewhat off-topic, but how about this trick?  (Where map is a plain array
this time.)

    map=(
    	'(*.(gz|Z))	zcat' 
	'(*.bz2)	bzip2 -dc'
	'(*.bz)		bzip -dc'
	'(*)		<'
	)
    eval 'for i do case $i in' ${(j( $i;; ))map} '$i;; esac done'
