Off, and on when in debugging mode.. Oops, the CVS version already does
this =) I also like the -D flag to z2.py. Now all we need is a interactive
DTML debugger through the web.

I didn't have too much trouble with it. Went from zilch python knowledge to
a fair grasp of Zope (and bothering the DC people with patches) in about
two weeks.

UML's will help clarifying and understanding what I find in the source.
Saves some grepping and debugging steps.

If all Zope developers lived by it, it would definitly help. The Ptree
protocol file (now gone in the CVS, I think) helped me understand the #tree
tag.

See above remark on the interactive debugger. Not too hard to do, but we'll
need multithreading to keep the rest of Zope moving. Oh, Zope 2 has that.

Only when someone with system level access has turned this on! It should be
off for many hosting sites, me thinks.

I'll give you a dollar?
