I'm not sure what you mean about overspecification here, but in setting 1/0 as +infinity (as opposed to -infinity), there's an easily overlooked assumption that the limit is obtained "from above" as opposed to "from below." -- Kim-Ee _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
