Not only that, but in Haskell, you don't really know 'n', it is only specified to be at least 23, or something like that. Which basically means that any code that relies on this behaviour without rigorously checking it basically is wrong. -k -- If I haven't seen further, it is by standing in the footprints of giants _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
