[Self-interest] Self implementations (was: Self implementation in Python)

[Russell Allen]

There is a place on GitHub for a Self wiki:

https://github.com/russellallen/self/wiki

People can add implementations there.

Wasn't there another Self in Java at one point? dSelf or something like that?

One interesting thing about both zigself and PySelf (for want of a name
:) is that they both seek to define a small subset of the Self
distribution as a core - booleans, collections, strings, etc.
