It's an "OnWard" what means a short (30-45 minutes) explanation of some work in progress.
Example Centric Programming it's an addendum to UnitTesting and TDD. The technic it's no very simple because it relies in hacking the compiler, so you can run a method without real compilation. So you could leave code branches without implement using a special character, while you increase your examples.
I like the idea but not the implementation since it depends too much in a very specific tool.
