While it is arguable whether the compiler should warn name shadowing by default, I believe unused local bindings should always be warned since: 1. such are dead code; 2. they almost always indicate a mistake by the programmer; 3. removing them only improves the clarity of the code. - Zhanyong _______________________________________________ Haskell mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell
