If you can live without OO, using lvalue subrutines with (\$) prototypes makes things cleaner: 

sub int_monitor (\$ ) :lvalue {
  my $var=shift;
  print "$var\n";
  $$var
};

There is no need for a prototype which also means you don't need to forgo the OO if you don't want to. 

sub int_monitor:lvalue {
  my $var=\shift;
  print "$var\n";
  $$var
};
