chai.use not working when using ES6 import

[mir3z]

Consider the following code

import { use, expect }  from "chai";
use(function (c) {
    console.warn(c.process.title) // echoes /usr/local/bin/node
});

So basically in this case I can't access chai.Assertion because global object goes as the first arguments to use.

This is most likely because use is defined as:

function (fn) {
  if (!~used.indexOf(fn)) {
    fn(this, util); // !!! this == global here
    used.push(fn);
  }

  return this;
}

@mir3z This is fixed per #724. It's available in the upcoming v4 release. A prerelease version is available through npm: chai@4.0.0-canary.1
