No for two reasons:
0. This is a translation of Abigail's post
1. Read Philips comment
Of course, abigails code can be made unambiguous my just changing
my $i;
to
my $i = 0;
But that was besides the point.
FWIW I never relied on either behaviour discussed in that thread. I tend to
always initialize my variable when appropriate, even empty hashes and
arrays;
