In Python I can do the following: 

a, b = 0, 1
while b < 50:
    print(a, b)
    a, b = b, a + b

That is shorter version of the following assignment (I think they call it atomic version):

old_a = a
a = b
b = old_a + b

How do I do the first assignment in Perl? My Perl version is

 
use warnings;
use 5.18.2;

my ($a, $b) = (0, 1);
while ($b < 50) {
    say "$a $b";
    my $old_a = $a;
    $a = $b;
    $b = $old_a + $b;
}

Thank you.
