That is very similar to what I have in mind for Maypole. But I don't think we
need that separation - one request object should be enough. I don't think we
need that complexity, but I think I understand why you need it for Catalyst.
Can you use custom context/request/response objects?

Yep. I'm going to add a lot of tracing, but the output will be configurable. I
think I'll be using Log::Trace when it's released:
