## Features

 - Binary functions...that's it.
 - Will always be less than 20 LOC (not including comments).
 - No dependencies.

## Anti-Features

 - Will not attempt to curry n-ary functions.
 - Will never `eval` your functions.

## Limitations

 - You will lose `fn.name`.

## API

### `curry2(fn)`

###### arguments

 - `fn: (Function)` Binary function to curry.
 - `[self]: (Object)` Function `this` context.

###### returns

 - `(Function|*)` If partially applied, return unary function, otherwise, return result of full application..

### `.uncurry()`

###### returns

 - `(Function)` returns original function.
