Go has an elegant approach to defining example functions, which are shown in docs as `main()` with the output:

I've been compilation buffers in Emacs recently and I really appreciate the error and warning counts shown in the modeline. I've added the equivalent feature to deadgrep: it shows result counts! Really useful when you're doing big refactorings.

Today I learnt about a cunning trick used by GNU diff to make Myer's algorithm faster: https://github.com/mitsuhiko/similar/issues/15 If you do an initial pass to find items that only occur on one side, you can discard them before diffing! They'll always be shown as changed.
