It looks right to me. :-) In the first case the NameError is caught by the except and not re-raised (but still enters the finally after the except block) and in the second the NameError is caught by the finally that does re-raise. What do you think should happen? Michael or shall I fill the bug?

Jean-Paul I think in python 2.x it's at least against the principle of least surprise. It should not behave differently.
