How can I detect for Generator objects in code?

[Raynos]

Currently I use

function isGenerator(obj) {
  return obj && Object.prototype.toString.call(obj) === "[object Generator]"
}

To detect a generator object which works in harmony but not in regenerator.

Is there an or clause I can add to feature detect generator objects from regenerator or should I duck test for .next() and .throw() ?

This is similar to #48

@Raynos We're addressing this in co with a fallback to checking constructor.name. Not bulletproof, but better than nothing...

I updated my function to

function isGenerator(obj) {
  return obj && (toString.call(obj) === "[object Generator]" ||
    // this fallback is here for polyfill runtimes, like facebook/regenerator
    (obj.constructor && 'Generator' == obj.constructor.name))
}

co has done the same.

@TooTallNate I added the same thing
