Problem on both using Babel babel/plugin-transform-classes and regenerator for async class methods

[a20185]

When using both, it seemed that the async methods in _createClass output lose the origin names, compared to the other non-async functions:

I found this was troublesome in some cases. Take runtime stack parsing as an example, now function was replaced by another function which name is not the same as original, hence we cannot figure out what function is really running at runtime(Because the error stack now shows at SomeClass.callee$ instead of at SomeClass.yourActualMethod )

I'm not quite sure about this transforming procedure machanism is done by babel itself or regenerator transform. An 'option' to preserve the function name, or providing enough infomation at execution will be really really helpful, thanks!
