This package defines the type class `MonadControlIO`, a subset of

`MonadIO` into which generic control operations such as `catch` can be

lifted from `IO`.  Instances are based on monad transformers in

`MonadTransControl`, which includes all standard monad transformers in

the `transformers` library except `ContT`.

Note that this package is a rewrite of Anders Kaseorg's `monad-peel`

library.  The main difference is that this package provides CPS style

operators and exploits the `RankNTypes` language extension to simplify

most definitions.

[This `criterion`](https://github.com/basvandijk/bench-monad-peel-control)

based benchmark shows that `monad-control` is on average about 2.5

times faster than `monad-peel`.
