Right, what I *can't* tell without installing PythonCAD myself is whether
that's the *only* glitch.  Since Diez's example died so early, can't guess
whether more problems appear after that one is resolved.

It better be, because I checked that change in for the next 3.3 pre-release
<wink>.  I think it should be fine.  "intSet" went away a loooong time ago,
and BTrees/Interfaces.py currently has a documentation-only role in ZODB.
Thank you!
