Playing with optional type signatures in Python, I realise that the return type is the most important to me. I'd much rather have a function with only a return type instead of a function with only parameter types. It's often quick to add too.

Today I learnt about Solargraph, an LSP for Ruby which includes an impressive amount of type inference and type checking! https://solargraph.org/guides/type-checking Type signatures are parsed from doc comments, similar to JSDoc with TypeScript.

I'm trying to factor out the interior mutability in my Rust code. It's a little more verbose, but surprisingly readable. foo_old(&syntax); foo_new(&syntax, &mut change_map); Signatures are way more self-documenting with this approach.
