John Smith proposed:
a failed pattern match should error in the same way as is does for pure code, while in MonadPlus, the current behaviour could be maintained with mzero

Any refutable pattern match in do would force MonadFail (or MonadPlus if you prefer).
I guess that would work out, but I think John proposed something else. Tillmann _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
