I would gain a 20% reduction in memory use, which could come out to a few gigabytes for large problems. That's worth some degree of effort. Actually, it'd be a bit less than 20%, but for large problems it would approach 20%. -- David Roundy Department of Physics Oregon State University _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
