A local variable is modified, but the global variable is printed.

This program looks almost the same, but there is no my inside the block. What does it print?

my $value = 100;

{
    $value *= 2;
}

say $value;

200 Answer: (: 1, 2, 100, 200 :) Without my, the block has no local variable, so it modifies the same global one.
