I'd use a slightly different term. Declaring a function that needs special precaution to be called as "safe", and declaring a function that is safe to be called anytime as "unsafe" is contra-intuitive. ;-) Peter _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
