[Zope-dev] Infuriating ZClass registry Heisenbug

[Casey Duncan]

Yes, except I would argue that such work is best left on the HEAD rather =
than=20
applied to a maintenance branch until necessitated by bug reports on that=
=20
branch, or at least the knowledge that such a bug definitely exists and c=
an=20
be reproduced on that branch.

I'm all for improving the code base. We just need to excercise caution=20
changing code on maintenance branches unnecessarily. The HEAD is another=20
matter, IMO go nuts!
