Actually, do notation is hardly necessary, about the only thing it really saves on is refutable patterns.


do
a <- m
b <- f a
return (a+b)


m >>= \a ->
f a >>= \b ->
return (a+b)

A bit uglier, but not any more complex, in particular, the parens are not necessary so you do not have to deal with matching a bunch of them.
