From CHANGES:
j. Associative array assignment and certain instances of referencing (e.g.,
`test -v') now allow `@' and `*' to be used as keys.
There are other ways to test whether or not an associative array has any
set elements, but there was no way to use `*' or `@' as a key in previous
versions.
There was a long discussion about this back in early 2021. Some of the
relevant messages about `@' and `*' keys start here:
