...i.e. I wouldn't be afraid of a lambda in a case like that. IME it's moderately common to have to do:
mapM_ (\a -> some stuff >> something_with a >> some stuff) ll
This has terrible endweight. In this imperativesque case, I'd write: forM_ li $ \a -> do some stuff something with a some stuff Where forM_ is from Data.Foldable (but is easily written as flip mapM_). Luke
