If I understand PEP 343 correctly, it allows for easy implementation
of part of your request. It doesn't implement the else: clause, but
you don't give a use case for it either.
class ignored_exceptions(object):
def __init__(self, *exceptions):
self.exceptions = exceptions
def __enter__(self):
return None
def __exit__(self, type, value, traceback):
try:
raise type, value, traceback
except self.exceptions:
pass
with ignored_exceptions(SomeError):
do stuff
I don't see the use, but it's possible.

If you're trying to write tests, perhaps a better use-case would be
something like:
with required_exception(SomeError):
do something that should cause SomeError
