### Is your feature request related to a problem or challenge? Any element of the array must be read. There are two ways to take elements from an array: through functions and through indices. Functions: Let's introduce two functions for reading one element and element range: - [ ] `array_element(array, i)` (read one element); - [ ] `array_slice(array, i, j)` (read element range); Index improvements: - [ ] additional key for slices (`array[i:j]`); - [ ] multiple index support (`array[0][0][0][0]`) - [ ] negative indices (`array[-1]`); - [ ] support for names indexes (`array[a]`); - [ ] arithmetic operations within an index (`array[1 + 2:3 + 4]`); ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
