Thanks for working on this issue. AFAIK crossbar abandoned Py2 support
in the newest version, so there is less to take of, but there are
still issues with Py3.7 and async keywords, that need to be resolved
first.

I don't know when I'll have time to update crossbar, so if you can
take over it would be great.

Thanks.

Yegor
