Also, consider enums. I think C++ only has the old, boring, C-style enums. 
Java managed to introduce quite an advanced enum facility, with the 
ability to attach custom methods and attributes to enum instances.

Python offers the same sort of thing as Java. Only, whereas Java enums are 
a feature that is built into the core language, Python does it as a 
standard library module, written in pure Python.

How do we do it? Metaclasses! (Also descriptors help.)

I’ll be waiting.
