Anyone integrated with surf with rdfextras 0.2-dev?

[Ming]

I've been using surf 1.1.4 with rdflib 3.1 and rdfextras 0.1 for some
time.
I just upgraded to rdflib 3.2 and there is no issue. Then upgrade to
rdfextras 0.2 (https://github.com/RDFLib/rdfextras), getting issue.

Just want to see if anyone see the issue??

I reported the issue to Graham and it is resolved
https://github.com/RDFLib/rdfextras/issues/42

However, as Graham indicated that it is not really backward
compatibility issues since there is no formal published API.
Since Surf is such a great work and also requires closely working with
RDFLib and its other components like rdfextras, would you folks
consider joining these folks? or already did:-)

They justhave a new home under https://github.com/RDFLib/
Thanks again for such a great work!!
