The reason "three" is printed is because "${a}[2]" is another way of
writing $a . "[2]" -- that is, you're explicitly separating the $a from
the [2], so that Perl doesn't think you're using an array.

This feels like a bug to me.

$x = "THIS";
my $x = "THAT";
print "${x} ${x}[2]\n";
THAT THIS[2]
I don't see why Perl accesses the GLOBAL $x when printing "${x}[2]". I
will file this as a bug.
