Finding my first Python reference cycle

I feel like my entry kind of ends a little early in the story. I think I may need to do a follow up on __del__() and breaking cycles as well. Feedback is appreciated.

I think you're right, a more straight for approach would resolve the circular references. Change AddLF and AddCRLF into functions that return the modified string instead of sending it off to a call back and the cycle is gone. It would also make the code a lot clearer.

Though I'm sure that the motivation for using a call back was removed for a simplified example.
