-If two array elements compare equal, their order in the sorted array
-is undefined. If you want equal elements to keep their order (i.e.
-you want a stable sort) you can write a comparison function that,
-if two elements would otherwise compare equal, compares them by
-their addresses.
+This is guaranteed to be a stable sort since version 2.32.

+There used to be a comment here about making the sort stable by
