When Python classes are pointless
This LiveJournal posting wound up raising the question of when one could or should avoid usingclasses to implement something. In Python, my warning signs are somecritical mass of:
- lots of NonMethodFunctions on the class.
- either every piece of data is part of the single object, or nothing is.
- only one object of the class is ever created by the program(as distinct from 'only one copy at any given time, but we throwit away and make a new one every so often').
