Dear all, the following DTML worked fine in Zope 2.6.2/Py 2.1.3: <dtml-let v="[x for x in ['a','b']]"> <dtml-var v> </dtml-let> Under Zope 2.7.0-b4 (python 2.3.3, win32), it fails with a NameError name '_getiter_' is not defined. The example is a variation of some actual code, stripped down to just expose the actual problem - in reality, we do something sensible with 'x' :-). Any idea about the cause?
