The other cases are where you want to do something in response to an
exception, but not otherwise::
def gen():
try:
yield
except:
print 'Got exception:', sys.exc_info()
raise
Personally, I think they're rare enough that you could use a decorator
in those cases, but still have::
def gen():
try:
yield
finally:
pass
automatically make the generator conform to the do/with protocol.
