Hello,
I suggest taking a quick look at the function ‘fold’ in Data.Foldable, and
also Data.Functor.Compose. That should be good start for composing any list
of such functions.
Cheers,
J.

Hi -
How can I generalize the following pattern to an arbitrary list of functions ?
compose :: (Monad m) => (Foo -> m Foo) -> (Foo -> m Foo) -> (Foo -> m Foo) -> Foo -> m Foo compose f1 f2 f3 acc = do a <- f1 acc b <- f2 a f3 b
Any help please .. regards.
