Hi all, Not sure exactly what this is called so cannot find a tutorial. Here is the code:

$a3 = "Hello";

$b = "a";
$c = "3";

$d = "${$b.$c}"; 

print $d;
# $d should be prints as Hello

[download]

This works fine, but if I change it a little:

$a[3] = "Hello";

$b = "a";
$c = "[3]";

$d = "${$b.$c}";

print $d;
# $d should be prints as Hello

[download]

It no longer works... What am I doing wrong?
Any help would be very much appreciated and thank you very much in advance!
