asyncio.async invalid syntax error in test suite

Hello,

Attempting to package this for Guix I encountered the following error:

Any idea?

Thanks for the report. Yeah, this issue appears because the library was written for earlier versions of python 3, before async was a keyword. Should be a straightforward fix; I don't know when I'll have time to get to it.

Looks like it's already fixed in 031c9750c74e3313b954b09e3027aaa6595649bb. A new release would help us packaging it :)

This issue is also affecting me.
