Generally speaking, kwargs in dispatch functions is a dangerous software engineering practice, IMO. I've debugged more function calls than I can remember, just because someone had mixed up functionality. > Adapters, Bridges, AbstractBeanFactories, and other stuff still causes me nightmares The "Javanic" approach is dreadful, I agree, but adapters and bridges (or really: using interfaces) can give you a clean and small design. I think that's what you're trying to achieve with "Pythonic if approach+composition using kwargs". But as usual, what's the best implementation depends on the context.
