I know a lot of you may like case insensitive languages, but it just feels weird for me. And there is the "nim" language which makes no distinction between CamelCase and snake_case.
Another thing to get used to is the ability to include characters in names that you normally can't, e.g., - and ?.
I'm not convinced that is actually a good thing. It really annoys me when two libraries for the same language use different naming conventions, and so far I haven't had any trouble with the strict casing rules in Haskell, or the casing conventions in Rust where the compiler emits warnings when you don't follow them (that you can disable with an annotation if you really need to).
