When using variable variables that are arrays, and you wish to print the value, you have to use a
temporary variable. For example:
print("${$a}[$index]");
will not work, use
$temp=${$a}[$index]"); print("$temp");
instead.
[Editors note: See the variable parsing section in types/strings. You can use
print "{${$a}[$index]}";
in this case
