Curry-this

Curry-this makes creating curryied function simple and expresive by invoking curry with the function bind syntax ::. Apart from the expresive way of creating a curried function, the main feature are placeholders. A placeholder (_) is a Symbol which allows to curry specific arguments of a function.

Install it: npm install --save curry-this

You can try this with babel-node. Make sure that you use the --stage=0 option.
