c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	2859 globals; they were simply stored as sys.exc_ZZZ. For backwards
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	2860 compatibility, they still are!) The problem was that in code like
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	2861 this:

c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	2871 cause of subtle bugs. I fixed this by changing the semantics as
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	2872 follows:
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	2873
c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	2874 - Within one frame, sys.exc_ZZZ will hold the last exception caught

c24a23b1f198 Added implementation notes for [re]set_exc_info(). Guido van Rossum <guido@python.org> parents: 28086 diff changeset	2882 bullet was for backwards compatibility: it was (and is) common to
