There is a difference between "enforcing a style convention" and "treating different style conventions as equivalent". The first is much preferable to the second (eg, you could easily enforce lowercase_with_underscore for identifiers and CamlCase for types).

Treating different conventions as equivalent, though, is an excellent of ending with code that looks visually different (library A can still use Capitalized_with_underscore identifiers everywhere while library B relies on lowercase everywhere, same with Bob and Alice working in the same codebase) but is the source of surprising behaviours.

If you want to enforce style conventions, either make them mandatory at the language level or write gofmt. The Nim "solution" is one of the things that kept me from even wanting to spend two hours checking it out.
