It is more important to be consistent and logical than to follow conventions and intuitions. And at any rate, convention is that 'isFoo' is a pure function with the type 'FooType -> Bool', clearly different from 'doesDirectoryExist', which returns an IO action. So IMO 'isDirectory "/foo/bar/"' should always return false, since it is a string, not a directory. -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
