I don't agree with your statement that "having handlers and loggers separate is not needed in real world scenarios". Maybe in your experience you haven't needed it, but I certainly have on more than one occasion. What I've found is that everyone's logging needs are different, and the rationale for having handlers and loggers as separate concepts is described in http://plumberjack.blogspot.com/2009/09/python-logging-101.html > I understand this point.

What I Well, I believe I've already covered this in PEP 391: http://www.python.org/dev/peps/pep-0391/#user-defined-objects You can instantiate stuff either using the default schema or use your own factories to construct the logging objects you need. I would say, if a simplifying layer is needed, it can be built on top of the proposed PEP 391 changes, and perhaps some usage patterns would become apparent over time to be so common as to justify putting in the core. Although the PEP refers to "user-defined objects", you can use a factory to instantiate any logging object, including instances of existing logging classes. And, don't forget the Zen of Python - "Explicit is better than implicit" ;-) Regards, Vinay Sajip
