this seems to be related to chaned appeared in python3.3: https://docs.python.org/3/whatsnew/3.3.html

by any chance, is there any way to make chaperone compatible with python3.2 ?

thanks anyway for this awesome piece of work :)

Unfortunately, the whole architecture of Chaperone does rely upon Python's new yield from statement as well as the asyncio module, which was not introduced until Python 3.4. So, 3.4 is really a minimum version. It was a tough decision actually, however, supporting older versions of Python would have introduced more dependencies (such as eventlet or Twisted) and that would have added to the requirement footprint.

I do have plans in the background to create a pure C++ version of Chaperone, but there is no time schedule for that yet. More and more people are starting to use it though, so it will bubble up on the priority list.

A pure GO version will be great :D
