Rust does something similar. It doesn't allow for brace-less clauses and it also bitches and moans at you about 'miss-using' camelCase, snake_case, etc. Which is great because it means that by default all project will follow a similar mark-up.

We also have 'rustfmt' in development, which goes even further than the built-in lints.
