cascade syntax for JS

cascade.js

// inspired by https://github.com/raganwald/homoiconic/blob/master/2011/11/sans-titre.md#readme

// traditional method chaining with combinators:
console.log(range(1, 3)
              .concat(range(4, 6))
              .map(function(x) { return x * x })
              .filter(function(x) { return x % 2 === 0 })
              .reverse());

// method chaining with cascades:
array
    ->pop()
    ->pop()
    ->pop();

path
    ->moveTo(10, 10)
    ->stroke("red")
    ->fill("blue")
    ->ellipse(50, 50);
