Isn't the MonadPlus approach also by-default-safe?

Safe, yes, but is it more useful?

Yes. In this case, take a parsing monad for example. You could write: parseInt :: CharParser () Int parseInt = do ds <- many digit readM ds And it would work automatically. A reading error would be propagated to the parser monad, and it would backtrack/report the error/whatever. Twan
