Cool.

So, the testing issue is biting you too. What to do? Are you testing 
both versions of the traits? I think this is probably the better way to 
go, but more work.

Hmm. OK.

Since we're both working on this, how should we stage this work?

Should I check what I have in, and then proceed immediately to the 
testsuite revamp? Once that is done I can add testcases for the new 
traits. I would like to work on parallel stuff if possible.
