And if it is (for which I'm not pushing), would it remove all occurrences or just the first one? Yes, it's officially supported (the relevant Guide chapter now reflects this). But it only works for arrays of strings, and it removes all occurrences from the array. I've also documented the use of a negative index with arrays: this works to remove an element from an array of any type, For example, one can use A = A[-2] to remove the second element from array A. Aha! So the natural follow-up question is: what about indexing vectors with this? Like A[- {1,3}] ?
