[![Build Status](https://secure.travis-ci.org/ekmett/either.png?branch=master)](http://travis-ci.org/ekmett/either)

This provides an `Either` monad transformer that unlike `ErrorT` is unencumbered by a constraint on its `Left` hand argument. This is needed for a number of applications of this monad transformer, notably in [recursion-schemes](https://github.com/ekmett/recursion-schemes).
