Ahh, yeah, then you definitely need the copy.copy call.
import copy
class ClassVars(type):

Sorry for not being clear.
Fresh copies of class vars so the first one is the correct: ('foo',
'bar', [], False)
>>> import copy

>>> class ClassVars(type):
... def __init__(cls, name, bases, dict):

Much better. Thanks again.

OK no question. I'm only posting b/c it may be something another newbie
will want to google in the future. Now that I've worked thru the
process this turns out to be fairly easy.
However, if there are better ways please let me know.
Module = ClassVars.py
import copy
class ClassVars(type):

If some one ever wants to build on this in the future, the current form
and use is:
import copy
class ClassVars(type):
classVars = dict(fields=[], longest=0) # adjust this
def __init__(cls, name, bases, dict):
for name, value in ClassVars.classVars.iteritems():
Hmm. setattr() only does a shallow search. Good to know.
Your
if not name in dict: setattr(cls, name, value)
is a more succinct/better way of writing
if not cls.__dict__.has_key(var): setattr(cls, var, val)
Which i tested a fair bit.
OK it appears that both are working for the simple
