Thanks Rowan,
That's a fair critique.
I expect some of the wording will be more clear once I write out the
documentation -- even if it isn't used directly, I tend to write out
documentation to force myself to reconcile the code with the plan, find logic
bugs, perform larger scale tests, and create tests to verify assertions in the
documentation. From there, I'll update the plan or code to get everything to
match and spend some time on clarity. It's the hardest part, IMHO, as it
requires diligently ensuring everything is correct. In other words, writing the
documentation makes it feel like a "real thing" and it triggers what small
amount of perfectionism I have.
