Today I Learned

You have to mull through a lot of terrible names, and iterate on terrible code to arrive at a consistent, reasonable API. Today I was building an ActiveSupport::Concern whose purpose will be to cache attributes that are expensive to compute. The names of the methods changed a handful of times. And even now they may not be finalized.

I left the code for a few hours, and returned to it with a fresh set of eyes. The names were terrible. Their implied meaning was confusing. But because of this gap, I was able to see some of of the consistent shortcomings. I also saw patterns emerging, that lead to a more consistent API for the final iteration (of the day).
