re seems to prefer sre over pre these days, so the following bit of Products/PythonScripts/module_access_examples.py no longer works: # from re import RegexObject, MatchObject # allow_class(RegexObject) # allow_class(MatchObject) The reason seems to be that sre doesn't define RegexObject and MatchObject, preferring instead to define types SRE_Pattern and SRE_Match, which can't be imported. Arguably this is probably a deficiency in sre, but as it stands, it seems to be currently impossible to use re inside of python scripts. I'm using an EM. I'll file a Collector issue on this one, unless someone has a solution, or someone wants to just take the 're' section out of module_access_examples.py.
