When talking about a match or a switch statement, I've typically seen people talk about individual 'cases' or 'arms'. TIL Zig uses 'prongs' instead!

Test code is total: we require it to always terminate or it's a failure! It also typically has 100% line and branch coverage. I feel way less nervous about refactoring tests, you can always just run them.

When a tool supports both regular expressions and literal strings, which should be the default? If you default to regex, users can match more strings than they realise (e.g. `foo.txt`) or less (e.g. `foo(bar)`). I typically see regex as the default, but I prefer the opposite.
