Perl swap two variables

This is a easy way to swap 2 ore more variables in a short and easy way in Perl.In this solution you don’t need a third variable as store.

my $a=37;
my $b=55;
print "a:$a b:$b n";
($a,$b) = ($b,$a);
print "a:$a b:$b n";

my $a=37;

my $b=55;

print "a:$a b:$b n";

($a,$b) = ($b,$a);

print "a:$a b:$b n";

And as result we get this:

a:37 b:55 
a:55 b:37

1 2	a:37 b:55 a:55 b:37

also happening using this post that i am reading now.
