Partiality *

Controversial? Perhaps; Opinionated? Certainly.

Derived from [Coco](http://satyr.github.io/coco/) and very like [CoffeeScript](http://coffeescript.org/). Even comes with it's own prelude.
[LiveScript](http://livescript.net/) and its related [prelude.ls](http://www.preludels.com/) aren't exactly [Roy](http://roy.brianmckenna.org/) or [PureScript](http://purescript.readthedocs.org/en/latest/) but do bring in much needed Haskell flavour to JavaScript. No strong static types here; just some syntax, like currying, pattern matching etc., to mitigate some of the pain and boilerplate in the Javascript land.
