Swish.Utils.ListHelpers

This module defines some generic list and related helper functions. The plan is to move to using functionality from other modules (e.g. containers) where possible.

subset :: Eq a => [a] -> [a] -> Bool

Subset test

equiv :: Eq a => [a] -> [a] -> Bool

Set equivalence test

flist :: [a -> b] -> a -> [b]

Apply list of functions to some value, returning list of results. It's kind of like an converse map.

This is similar to the ap function in the Monad library.
