Is there some sort of equivalent of the if/then/else construct for use in the IO monad? For instance the following can get quite tedious:
> do bool <- doesFileExist filename > if bool > then sth > else sth' Is there a more compact way of writing that? Something akin to: > condM (doesFileExist filename) (sth) (sth') Or maybe there's a more sensible way of doing the above that I've missed. I seem to use endless alternate conditions sometimes and there's bound to be a better way. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
