Nitpicking, but Go is one of the only languages I’m aware of where identifier case is semantically relevant (to determine visibility). Given that fact it’s hard to say “nothing” enforces a case standard.

Adding to that, the compiler doesn't enforce using "mixed caps", as the documentations calls it, but it's strongly recommended (https://go.dev/doc/effective_go#mixed-caps)

Haskell enforces that types and type constructors start with Uppercase, and that everything else starts with lowercase.

I can't imagine why this attitude pervades on hacker news. I can't imagine a more trivial reason than yours to make a reply.

I guess some people see this as a place to discover differences, and others see it as a place to enforce blind conformity to the current fad.
