Square brackets: lists and indexing
Behavior and details
Square brackets create a List when used as a primary expression, or index a preceding value. List items are comma-separated and may span lines with a trailing comma. An index must refer to an existing element or Map key. Brackets do not provide slices, ranges, or comprehensions.
Example
# language: en
let items = [10, 20, 30,]
say items[1]
