Hi again, Forgot to mention this in my last email. I find myself writing a lot of if-then-elses in do notation, and most often the else branch is "return ()". This gets a bit cumbersome to write and messes up the code.
So now I tend to use: doIf :: Monad a => Bool -> [a b] -> a () doIf b e = if b then sequence_ e else return () I find the list of computations to be quite flexible and neat. There are probably plenty of variations on this idea you can try. Cheers, Bernie. _______________________________________________ Haskell mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell
