TDDbE: Equality for All, Redux

 I tried this already

I'm not entirely sure how I want to interpret this remark.  On the one hand, spikes are a thing, and we might reasonably run some quick experiments in a sandbox to guess which approach we would prefer to use.  On the other hand, cooked examples are a thing; demonstrating a practiced solution is not nearly as compelling as demonstrating an unpracticed solution.

I'm not fond of this demonstration at all.

In order, it's hard to tell at this point if we're supposed to be learning that this is the way to do it, or if this is intended to be some flavor of "even though we started badly, we got there in the end."

Maybe it's a lesson about choice - introducing the complexity of Francs before we've invested too much in Dollars reduces the cost of change, with the penalty of having more "not yet done" things to keep track of?

It's hard for me to shake the notion that the viability of this approach is tightly coupled to the fact that this is a toy problem.
