At least it doesn't force any casing on you, as some languages do.

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).

We, as programmers, will never convince anyone that our preferences are right for everyone else, even when there are strong technical arguments. In this case (pun intended), it's subjective. A lot of it is what we get used to.

I consider Nim's approach an advantage since it prevents nasty confusion by accidental typos, in particular in big projects with many modules.
