[Zope-dev] Syntax error in python2.6

Hi everybody, During the porting of Zope2 to Python2.6, I am stuck with a syntax error in the module AccessControl, which is given below. def reorder(s, with=None, without=()): ^ SyntaxError: invalid syntax in line 56 of /home/zope/ztrunk26/lib/python/RestrictedPython/Utilities.py. The same code when run in python2.4 and python2.5 didn't give any syntax errors. Can anybody suggest the reason for this syntax error in python2.6.
