Ah, I missed that point about the new kwargs mechanism! Before I was +0 on
*args/**kw, now I'm +1. I've actually needed that feature more than once,
but have been doing it with specialized in-body class decorators, like this:
class FooService(context.Service):
context.replaces(BarService)
...
Which could presumably now become:
class FooService(context.Service, replaces=BarService):
...
Right?
