best way to write a-> ..->[a] recursive functions in haskell
- by Roman A. Taycher
So I keep having this small problem where I have something like
func :: a -> b -> [a] -- or basically any a-> ...-> [a] where ... is any types ->
func x y = func' [x] y -- as long as they are used to generate a list of [a] from x
func' :: [a] -> b -> [a]
func = undefined --situation dependant generates a list from each element and returns it as one long list
should I keep it like this?
should I use func' hidden by a where?
should I only use the [a] - b - [a] version and leave the responsibility of passing [variable] to the callee?
I might well need to compose these functions and might want to mess around with the order so I'm leaning towards option 3. What do you think?
