That's idiomatic go. See https://go.dev/blog/generate https://go.dev/blog/generate and '//go:generate stringer -type=Pill' See also '//go:embed', which also turns a variable into a magic type via an ad-hoc comment-only DSL. In go, it is idiomatic to say "macros slow down compilation and often require a second pass, go compilation is fast, macros are bad", and then also to have an extra "make sure go generate is up to date" CI step which parses your go codebase 10 more times, forks dozens of processes, and isn't type-safe since of course it's not it's literally a comment you can typo "//gog:enerate" and no one will notice.
