Three Dollar Quill

• Wednesday: I started working on red-black trees using Structured Data.
• Thursday: I finished the first iteration of red-black trees, which generated yet another feature idea to try to improve the ergonomics.
• Friday: I thought more about type-checking.
• Saturday: I revisited the feature idea, then realized my initial concept was way too complicated.
• Sunday: I got the feature done, then looked into addressing coverage gaps.
• Monday: I closed as many gaps as I felt comfortable with, then went to bed as soon as I could.

Next week, I want to take a break for a bit to focus on writing, then come back and work on improving the type coverage.
