Three Dollar Quill

• Wednesday: I got a new matrix operation written.
• Thursday: The matrix documentation has problems.
• Friday: I fixed one of those problems.
• Saturday: Pain.
• Sunday: I started identifying specific issues with the matrix module.
• Monday: I reviewed the matrix module to find problems, although some of them were basically just "the vibes are off".

Next week, I'm going to try to take a break from this and focus on some other projects for a bit.
