* Use regenerator-transform to implement babel-plugin-transform-regenerator. Though I believe this is safe to merge, you may want to wait to merge it until https://github.com/facebook/regenerator/pull/259 is merged. That pull request also provides more explanation of why I think moving the implementation of Regenerator back to its original repository is a good idea. I'm happy to compromise on anything necessary to make this happen. Note that the regenerator-transform version is pegged to an exact version (0.9.7). Past experience has taught me that releasing new versions of Regenerator is almost impossible if client projects are allowed to pull in new patch versions automatically. I will happily submit a pull request whenever a new version is released. * Remove never-used babel-plugin-transform-regenerator/.test directory. * regenerator-transform to 0.9.8

Transform async/generator functions with regenerator

while (1) {
switch (_context.prev = _context.next) {
case 0:
_context.next = 2;
return 1;
case 2:
case "end":
return _context.stop();
}
}
}, _marked[0], this);
}
