Very nice. Python std lib is growing more data structures, increasing the power of a default Python installation. I can remove more and more modules from my bag of tricks. I like the name Bag(), it's shorter. Names are important enough. Are keys restricted to be long and int values only? Or are they general (referenced) objects + a control of their integral nature? I think you can add better explanations to this, like an example: c += Counter() # remove zero and negative counts Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
