I guess I'm wondering if we need a with...except construct so that we can get exceptions that happen after the with context is entered without wrapping the with statement in try...except.

Would this hypothetical construct:
with some_context_manager() as obj: do_something_with(obj) except Exception: error_handler()
catch exceptions in the context manager, the do_something_with() block, or both? Give reasons for why you make that choice.
-1. As Steven hints, this will just cause more bugs because people won't guess the right semantics for corner cases, and corner cases are all what except clauses are about.
