Subject: RegExp outermost ()

This may be a case where RegExp ain't the way to go, but I want to scan 
a string with nested paren groups and extract each outermost group. Is 
this best done in an RegExp?

s = 'a group ( stuff ( other )) (( hey ( you ) (there) ) stuff )'

magic_re = # ?
s.scan(magic_re) { |match| puts match }

output:
( stuff ( other ))
(( hey ( you ) (there) ) stuff )
