Logically that should only unset the elements of an array and not the
array variable
itself since '*' or '@' is more of a wildcard that represents the
indices.  However, bash
does otherwise:

  #define ALL_ELEMENT_SUB(c)    ((c) == '@' || (c) == '*')

...

  if (ALL_ELEMENT_SUB (sub[0]) && sub[1] == 0)  // If substring is
just '@' or '*'
    {
      unbind_variable (var->name);  // It just removes it.
      return (0);
    }

Bash version is 4.3.33.
