That violates an important convention in Python: mutating methods do not return self. We really want to preserve that convention. On the other hand, as seen in other recent threads, there is a desire for chaining operations of many sorts, so a .flow_update() that returned a new dict would provide that feature. Though I would only recommend that if it was decided that we wanted to generally support that approach for all mutable containers — which would mean adding quite a few methods. And we could then use the same naming convention for them all. I’m not sure I like “flow_” though, it’s not very commonly known jargon. -CHB -- Christopher Barker, PhD Python Language Consulting - Teaching - Scientific Software Development - Desktop GUI and Web Development - wxPython, numpy, scipy, Cython
