       The Perl model for function call and return values is simple: a
+ll func-
       tions are passed as parameters one single flat list of scalars,
+ and all
...
       many or as few scalar elements as you’d like.  (Often a functio
+n with-
       out an explicit return statement is called a subroutine, but th
+ere’s
       really no difference from Perl’s perspective.)

   sub print_person {
      my $address_hashref = shift;
...
   my @hobbies = ( "flying", "mountain climbing" );

   print_person(\%address, \@hobbies);
