How can I combine these two cases together (or otherwise simplify the code)?
I don't know if I'm understanding you correctly, but something like this?
f a = do case g a of Nothing -> return () Just b -> do h a (field1 b) (field2 b) i a (j a) (field1 b) (field2 b)
To take this a step further, if 'field1' and 'field2' are projections, then you might be able to replace them with pattern-matching as well: f a = do case g a of Nothing -> return () Just (Constructor f1 f2) -> do h a f1 f2 i a (j a) f1 f2 I know this is just a made-up example and not real code, but figured it was worth mentioning anyway. -Brent
