[Zope-dev] Intersection (set) in Zope

[Jason Spisak]

Does anyone know if Zope already has (I'll bet it does, it's just a
matter of finding it, which I haven't yet) an object or method for
intersection or set of two lists.  I want items common to both lists. 
It's a simple python external method, but why write code t hat's already
written.  I combed the dtml guide and the source in places and can't see
what it would be called.  Any ideas?
