When to freeze, clone or dup in Ruby?

I try out expressing my intent in different forms to see what works effective. This time around, I'd like to story tell the code as if it's evolving over a pair-programming session. I'd appreciate your constructive feedback. Warning the examples in story you're about to read might be super contrived and redundant. I'm merely trying the story-telling way to explain concepts with examples in the hope that you get near first-hand experience of pair-coding and experience learning. Chew on the concept leaving the contrived examples and story behind :P

The file extension is excluded in the case of require method.
