I seem to be settling into a pattern of solving these on alternate days. Late for one round, early for the next.

Day 4 solutions (spoiler alert):

http://akkartik.github.io/mu/html/apps/advent2020/4a.mu.html

http://akkartik.github.io/mu/html/apps/advent2020/4b.mu.html (utterly ghastly)

2.5 hours. 2 machine-code bugs found, 1 new (terribly named) library primitive added: https://github.com/akkartik/mu/commit/18d5bab2b66

Day 5 solutions:

http://akkartik.github.io/mu/html/apps/advent2020/5a.mu.html

http://akkartik.github.io/mu/html/apps/advent2020/5b.mu.html

30 minutes. No new Mu bugs found.
