FWIW, the Zope3 style guide on that wiki page states explicitly in the
first paragraph that Python Style Guide is used for all issues that are
not mentioned, and then continues to say that "most of the code" in
Zope 3 so far uses CamelCase instead of names_as_this.
The way I read this, it's "most of the code so far uses", rather than
"all code must/should use". It's a *description* of the current state
rather than the *prescription* to do it in CamelCase.
Perhaps the intent to prescribe should have been stated explicitly,
but currently it isn't, it's only nudged towards a new user.
I also think this is the least worthy of style issues to pursue because
it affects the reader's visual perception. All of us have different
visual perceptions, some of us have bad eyes or some other reason to
find one easier to read than other. Please see my other message in
this thread on this.
+1 for Benji's preference of PEP-8.
