map package:ghc

map f xs is the list obtained by applying f to each element of xs, i.e.,
map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn]
map f [x1, x2, ...] == [f x1, f x2, ...]
>>> map (+1) [1, 2, 3]
Apply a function to each element of a Stream, lazily
Changes all labels mentioned in the SwitchTargets value
The [CoAxBranch] passed into the mapping function is a list of all previous branches, reversed
The mapAndUnzipM function maps its first argument over a list, returning the result as a pair of lists. This function is mainly used with complicated data structures or a state monad.
Map each element of a structure to a monadic action, evaluate these actions from left to right, and collect the results. For a version that ignores the results see mapM_.
Map a free variable computation over a list and union the results.
