Hello,
I have a conflict between regenerator and the way Iterator is polyfilled that I mentioned on regenerator's repo: facebook/regenerator#320.

The problem is regenerator uses IteratorPrototype for its GeneratorFunction, and it crashes when it tries to write on GeneratorFunction.prototype.toStringTag which is not writable.

The spec mentions no toStringTag property for IteratorPrototype:
https://tc39.github.io/ecma262/#sec-%iteratorprototype%-object

Is it possible to remove toStringTag from IteratorPrototype?
