Same way you return a string, or a number, or anything else: you don't.

Functions in bash aren't actually functions.  They're user-definable
commands (procedures).  Asking how to return a list from a function is
exactly like asking how to return a list of filenames from "ls" or "find".

Hell, you can't even pass a list IN as a value, let alone RETURN one.
