[Python-Dev] Deprecating string exceptions

Zope 2 uses them heavily.  But I doubt it will ever need Python 2.4;
more likely, it will settle on Python 2.1.3 (if/when that is
released).

In Zope 3, string exceptions are officially out of grace.  (I don't
know if there are any left, but if so, they will be removed soon
enough.)
