If you want to check whether an array variable is set, you can check
whether it has any set elements:
(( ${#assoc[@]} > 0 ))
This doesn't check whether an "array variable is set".
It checks whether there are any set elements. You have to assign a value
to set a variable.
Not only that, but the test will be true in the case that assoc has been
defined as a variable that is not an array.
One hopes that the shell programmer knows what variable types he's
using, and uses the appropriate constructs.
