Further to this (not that this thread isn't long dead), in Terje Kristensen's latest minigolf competition he came up with this: 
-n $;[map{/./,/[^$&-T]/g}/(?=(.*))/g].=$_}{print@

[download]
Which does funny non zero width things for (?=) 
perl -le 'print for "foo bar"=~/(?=(.*))/g'
foo bar
oo bar
o bar
 bar
bar
ar
r

[download]
I had no idea this would happen, anyway.
