Awful. It reminds me on MatLab where the developers have implemented many automatisms which do arbitrary clever things in every corner case, but nothing consistent, because they thought programmers want it that way. Then the programmers must write wrappers in order to get functions with consistent behaviour around the fully automated functions. The "unlazying" procedure looks much like the "lazying" one, and I wonder whether it would be a good idea to eventually add "readFileStrict", "getContentStrict" and "hGetContentStrict" to the standard library. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
