Citrine is also 1-indexed (https://citrine-lang.org/#lists), I think this would help people who are not developers to read and possibly verify code a bit easier. Of course it is just a small step, but I feel code in general is drifting away from the normal users, who seems to be confine to graphical interfaces. Wasn't it an objective once in the software development community to try and make code as accessible as possible?
