Not really. There is a procedure for making non-backwards compatible changes. If you care deeply enough about this, you could agitate for Python 3.2 to raise a PendingDepreciation warning for "unexpected" escape sequences like \z, Python 3.3 to raise a Depreciation warning, and Python 3.4 to treat it as an error. It may even be possible to skip the PendingDepreciation warning and go straight for Depreciation warning in 3.2. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
