Mocha opts
0.7.0
0.8.0
Added polyfill to lib instead of node_modules, because now it's added to the npm package.
0.8.1
It not supports filter out of the box, or all cases where the items in the array are not edited in the iteration, so the output could still have promises inside.
Will fix it more later, to be really out of the box.
Also has tests!
0.8.2
0.8.3
Made it create two methods, for when one of them is taken by the promise implementation.
