Very interesting. Though I remember Uri wrote the original File::Slurp (which I never used because I hate dependencies) I didn't know about Sort::Maker.

I remember Uri well from the early Perl Golf days (e.g. search for Uri in The Lighter Side of Perl Culture (Part IV): Golf) though I never met him in person. He seemed to be a lovely guy and an entertaining character, famous back then for his beard, pony-tail, glasses - and a penchant for tie-dyed T-shirts. :)
