That's not a realistic example. If you were printing two variables, it would look like
print $name, ", ", age;
or
print "$name, age";
And neither looks similar to the following to me:
print $fh $age;
As for your Perl6 eaxmple, you can do the same in Perl5.
$fh->print($s); # Perl5
$fh.print: $s; # Perl6
