Description
Functions that simulate the behavior of regular patterns using a Match monad for parsing lists.

The Match monad
runMatch :: Match e a -> [e] -> Maybe aSource
baseMatch :: (a -> Maybe b) -> Match a (a, b)Source
manyMatch :: Match e a -> Match e [a]Source
gManyMatch :: Match e a -> Match e [a]Source
foldComp :: [[a] -> [a]] -> [a] -> [a]Source
unzip0 :: [()] -> ()Source
unzip1 :: [a] -> [a]Source
unzip2 :: [(a, b)] -> ([a], [b])Source
unzip3 :: [(a, b, c)] -> ([a], [b], [c])Source
The unzip3 function takes a list of triples and returns three lists, analogous to unzip.
unzip4 :: [(a, b, c, d)] -> ([a], [b], [c], [d])Source
The unzip4 function takes a list of quadruples and returns four lists, analogous to unzip.
unzip5 :: [(a, b, c, d, e)] -> ([a], [b], [c], [d], [e])Source
The unzip5 function takes a list of five-tuples and returns five lists, analogous to unzip.
unzip6 :: [(a, b, c, d, e, f)] -> ([a], [b], [c], [d], [e], [f])Source
The unzip6 function takes a list of six-tuples and returns six lists, analogous to unzip.
unzip7 :: [(a, b, c, d, e, f, g)] -> ([a], [b], [c], [d], [e], [f], [g])Source
The unzip7 function takes a list of seven-tuples and returns seven lists, analogous to unzip.
