Make module available without polyfill

[qubyte]

It would be nice to be able to require fetch without it being appended to window in a similar way to the es6-promise polyfill. If fetch can be assigned to a variable, then this means that when a broken or otherwise incompatible version of the fetch API become available in a browser, code that uses fetch won't break.

In other words:

// This fetch can be used as is.
var fetch = require('fetch');

// Do this only if you want to polyfill fetch on the window object.
fetch.polyfill();

I realise however that this breaks the existing API.

This library is just going to be a standard polyfill implementation.

That module just does the same as this one, but works in Node too. i.e. the behaviour in the browser is identical.

One last try to convince... doing this will allow your users to protect themselves from differences in implementation and changes in spec as browsers evolve.

Else, I can close (or please feel free to).

This is what I'm using at the moment. Seriously ugly, but has the behaviour I want: https://gist.github.com/qubyte/21cade5e28c924c48bc1

I put that gist into a library. It has one potential showstopping problem though... It means that the brfs transform must be used globally. https://github.com/qubyte/fetch-ponyfill

@qubyte you can specify transforms on a per-package basis (e.g. in your fetch-ponyfill package.json) to avoid the global-ness.

@domenic Wow. I really should have realised that. Thanks for the tip!
