I agree with your use case.
Just today, I was writing python code to wrap and reraise exceptions, albeit
not having to do with channels
class WrappedException(Exception): pass
...
except Exception:
raise WrappedException(sys.exc_info())
...
except WrappedException, e:
raise self.wrapped.args[1], None, self.wrapped.args[2]
If your patch doesn't already do so, I'd suggest that send_exception can take
up to three arguments, with the same semantics as "raise"
Cheers,
K
