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][].
``` hs
import Flow
```

`f .> g` | `f >>> g`
`g <. f` | `g . f`
`compose f g x` | `g (f x)`
`x !> f` | -
