I could use a pattern like this:
except Exception as e:
and then after receipt of a value from c do:
if isinstance(value, WrapperException):
I could also subclass channel to change the default behavior of send_exception and receive to behave in this manner, but this at least partially defeats the point of having a builtin channel.send_exception. Extending the semantics of send_exception to allow passing an exception instance seems preferable to either of these other approaches.
