in thread The @_ array and the lexical variables

Could you demonstrate that behaviour with a normal array or how I would arrive at that behaviour? Something like: 
my @arr = (my $one, my $two, my $three);

    No, it's the magic behind @_ and calling a subroutine that causes the aliasing. Normal arrays don't alias.

    Another aliasing construct if for:

    my $x = 1;
for my $y ($x) {
    $y++;
}
print $x;  # 2

    our @arr; local *arr = sub { \@_ }->( my $one, my $two, my $three );

    or 
    use Data::Alias qw( alias );

alias my @arr = ( my $one, my $two, my $three );

    or 
    use feature qw( refaliasing );

my @arr;
\$arr[@arr] = \my $one;
\$arr[@arr] = \my $two;
\$arr[@arr] = \my $three;
