How much code from asyncio did you reuse ? How deep was the porting
effort ? Is the port maintainable as asyncio gets more bugfixes over time ?

Could we use a helper library (like six) to have the same syntax in Py2
and Py3 ? Something like "from six.asyncio import yield_from,
return_task" and use those functions for py2/py3 compatible syntax ?
