The sensible way to dump the entire 3D array is:
foreach (@MyArray) {
foreach (@$_) {
foreach (@$_) {
print "$_\n";
}
}
}

A 1
A 2

B 1

But that isn't the order your code assigned them, which increments the
2nd index followed by the 3rd followed by the first. Here they are
printed in the order 3, 2, 1 as you'd expect.
