aboth, mapPair, et al

Various utility functions for pairs and lists

Types

aboth :: (a -> b) -> (a, a) -> (b, b)
mapPair :: (a -> b, c -> d) -> (a, c) -> (b, d)
pairwith :: (a -> b) -> a -> (a, b)
swap :: (a, b) -> (b, a)
pair :: a -> b -> (a, b)
oo :: (a -> b) -> (c -> d -> a) -> c -> d -> b
anth :: Int -> (a -> a) -> [a] -> [a]
number :: Int -> [a] -> [(Int, a)]
loop :: (a -> a) -> a
gmap :: (a -> [b] -> [b]) -> (c -> a) -> [c] -> [b]
unionmap :: (Eq b) => (a -> [b]) -> [a] -> [b]
remove :: (Eq a) => a -> [a] -> [a]
replace :: (Eq a) => (a, b) -> [(a, b)] -> [(a, b)]
lhead :: [a] -> [b] -> [b]
ltail :: [a] -> [b] -> [b]
lsplit :: [a] -> [b] -> ([b], [b])
part :: (a -> Bool) -> [a] -> ([a], [a])
issubset :: (Eq a) => [a] -> [a] -> Bool

Description

These are various small utility functions missing from the standard Haskell libraries.
