[ros-users] ROS for Python3

[William Woodall]

Thanks Ken, I was aware of the work these guys are doing, I have just run
into some issues and solved them, but still want to make sure my fixes are
working in both Python 2 and 3 so I do a lot of switching.

That brings up something else I was wondering.  If I find/fix something
should I go through the proper trac ticket process or should I go
through Michael Karg, Séverin Lemaignan, and Lorenz Mösenlechner so they can
be rolled into broader patches like the ones on trac right now?  I guess
what I am asking is whether or not the move to support Python3 is solid
enough to move to bug reporting or if it is still fluid enough for patching
in larger patches.
