bound.js

// Motivation:
//
// I see myself writing this quite often:

f(_.bind(obj.m, obj))

// but I could write:

f(bound(obj, 'm'));

// @evilhackerdude v1
function bound(object, fn) {
  return _.bind(object[fn], object);
}

// @raganwald
function bound(object, fn) {
  return object[fn].bind(object);
}

// @evilhackerdude v2
function bound(object, fn) {
  return function() {
    object[fn].apply(object, arguments);
  };
}

I have some code that can force an arity in allong.es, I use it precisely because I wanted to make sure that everything interoperates with curry and partial application. We could look at whether to "improve" bind such that it preserves length even in older browsers.
