Actually, the loop variable will be lexical if there's a current lexical variable with that name, otherwise it will be local variable (with a local scope). 
my  $i = 10;
our $j = 10;

sub print_it {say "[$i, $j]"}

print_it;
foreach $i (0 .. 5) {print_it;}
print_it;
foreach $j (0 .. 5) {print_it;}
print_it;

__END__

As you can see, $i is lexical, and its value isn't visible outside the loop. But $j is a package variable, who gets a localized value inside the loop. And then its value is visible outside the loop.
