Hi Chris, I’d like to share my thoughts on the array syntax. I agree with the survey results; I think they are the clearest options. However, in my humble opinion, there should be one—and preferably only one—obvious way to do it (paraphrasing The Zen of Python). Having multiple equivalent syntax options (the result of adding [5] and [4][6], in your example) could lead to confusion and ambiguity. I’d prefer to keep it as simple as possible.
Please let me know if I’ve misunderstood anything. Kind regards, Andoni
