I have noticed that many projects include a 'concatMapM' function:
concatMapM :: (Monad m) => (a -> m [b]) -> [a] -> m [b]
I think this is useful in general, so let's add it to Control.Monad.
the one thing that you miss - each time you add popular function to the base library, all programs that include this function becomes incompatible with next GHC version. i wonder whether anyone here has the experience of writing large programs and maintaining them through the years? -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
