Re: [Modeling-users] Interfaces

[Sebastien B. <sbi...@us...>]

This initially came from zope (not z3 but some good old z2). When I
began coding the framework, I used interfaces as a guideline for
forthcoming implementations. I also used zope's Interface class to make
some verifications --there's an example of this in KeyValueCoding, look
at the end:

  try:
    verify_class_implementation(KeyValueCodingInterface, KeyValueCoding)
  except:
    pass


Now back to z3 and twisted, I wish I had the time to discover those
masterpieces, but unfortunately that's not (still!) the case...  BTW if
any of you have (even little) experiences w/ MDL and z3 or twisted, I'm
very interested in hearing your stories!
