Flow
Write more understandable Haskell.
Flow is a package that provides functions and operators for writing more
understandable Haskell. It is an alternative to some common idioms like
($) for function application and (.) for function composition.
Requirements
Flow requires a Haskell compiler. It is tested with recent versions of GHC, but older or different compilers should be acceptable. For installation with Cabal, Flow requires at least Cabal 1.8.
Installation
To add Flow as a dependency to your package, add it to your Cabal file.
build-depends: flow ==1.0.*
See the change log for a detailed list of changes.
Usage
Flow is designed to be imported unqualified. It does not export anything that conflicts with the base package.
import Flow
