  1. You should definitely take a look at Moose.

    package Point; use Moose; # automatically turns on strict and warnings  has 'x' => (is => 'rw', isa => 'Int'); has 'y' => (is => 'rw', isa => 'Int');  sub clear {     my $self = shift;     $self->x(0);     $self->y(0); }

    Moose gives you (among other things) a constructor, accessor methods, and type checking for free!

    So in your code you can:

    my $p = Point->new({x=>10 , y=>20}); # Free constructor $p->x(15);     # Free setter print $p->x(); # Free getter $p->clear(); $p->x(15.5);   # FAILS! Free type check.

    A good starting point is Moose::Manual and Moose::Cookbook

    If you just need the basic stuff you can also use Mouse which is not as complete, but without most of the compile time penalty.
