[Zope-dev] ZPatterns: Methods of specialits

[Roch'e Compaan]

I have a specialist Contacts and for Contacts I have a method
getAllContactsForCustomer.  Whenever I want to call this method I have to
pass on the whole namespace and the object itself to get it to work eg:
getAllContactsForCustomer(this(), _, _.None).  Why is this the case?  And
what does _.None actually mean?
