I need a speedy version of the Array.combination method. Unfortunately the C implementation of this method is only available in ruby 1.87 while we are tied to 1.86. Is there a way to backport and monkey patch the combination method from ruby 1.87 into ruby 1.86. I''ve been playing with ruby inline but so far no luck. Of course my experience to C was limited to my college days way back when so it''s no surprise. thx. -karl
