Benny - This sounds like a very interesting idea. I'd like to try to make it more general. There are lots of other __xxx__ methods that might also be usable. generateDS.py already has a facility for reading method bodies from a file for special validation methods. See the notes on "simpleType and validators" in the documentation (http://www.rexx.com/~dkuhlman/generateDS.html). What if we were to generalize that still further so that you could provide an external file containing a list or dictionary of the following triples: (1) one or more element/class names (or possibly a pattern), (2) a method header, and (3) an implementation body? Give me a day or two to think this through and present you with a proposal. I suspect that I will have a few questions, for example: 1. How would you specify that a method should be generated for a set of classes or for all classes? With a wildcard characters or a regex (regular expression)? 2. How would we parameterize it? Do we need some way to do string replacements into the body of the method? 3. Does your __eq__ method need to know (the names of) all the member variables and perhaps their types? Perhaps generateDS.py could generate a class variable containing this information. I'm not sure. Need to check. As you can tell, I'm groping here. Give me a bit more time to think on it.
