I used to be skeptical about introducing complex expressions to C-syntax languages for a long time until I saw how well Kotlin handled `when`. Now every time I use typescript or go I have trouble trying to express what I want to say because `when` and similar expressions are just such a convenient way to think about a problem. In go that means I usually end up extracting that code into a separate function with a single large `switch` statement with every case containing a `return` statement.
