And I should have submitted a patch to the collector instead of posting here. :-(
Just not sure what is the "right" way to do this, here's my first pass:
def guarded_reduce(f,seq,**kw):
skip_unauthorized = kw.get('skip_unauthorized')
v = getSecurityManager().validate
safelist = []
if kw.has_key('init'):
i = kw['init']
if v(accessed=kw,name='init',value=i):
safelist.append(i)
elif not skip_unauthorized:
raise Unauthorized, 'unauthorized access to init'
for el in seq:
if v(seq, seq, None, el):
safelist.append(el)
elif not skip_unauthorized:
raise Unauthorized, 'unauthorized access to element'
return reduce(f,safelist)

[Zope-dev] reduce() doesn't work in Python Scripts
In Zope 2.4.3 binary on Linux import operator reduce(operator.add,[0,1,2,3,4]) gives me Error Value: global name 'reduce' is not defined Is this a faq?
