As I said, this feature was only introduced in bash 5.1, and the version
with an expansion does not work in either bash 5.1 or 5.2.  There is no
version of bash in which it works.

You can try it yourself.

Whatever you were doing before probably involved eval, or some other
form of code injection through multiple layers of shell parsing.
