[Zope-Checkins] CVS: Zope/lib/python/TAL - TALInterpreter.py:1.61

[Jeremy Hylton]

Update of /cvs-repository/Zope/lib/python/TAL
In directory cvs.zope.org:/tmp/cvs-serv8273

Modified Files:
	TALInterpreter.py 
Log Message:
Revert previous checkin.  TAL must work with Python 1.5.2.

XXX Future issue to resolve: How to shut up deprecation warnings in
the test suite when running with Python 2.2.  The Zope trunk isn't
required to work w/ 2.2 yet, so it's a non-issue at the moment.
