Loading es6-shim after prfun clobbers prfun on Node

See paulmillr/es6-shim#297

Note that prfun automatically loads es6-shim if there are no Promises defined, so what's happening here is that the native platform has a Promise definition, but it's buggy so es6-shim replaces it.
prfun should use the same "are Promises buggy" test that es6-shim does, probably.

Note that you can workaround this as shown in the README:

var prfun = require('prfun/wrap');
require('es6-shim'); // optional
var Promise = prfun(globals.Promise);

Thanks. To that end, I imagine I can also do:

var promisify = require('prfun').promisify;

Then, it won't matter if prfun gets clobbered or not.

In version 2.0 prfun creates a Promise subclass, rather than clobbering the global Promise.
