in reply to Object Oriented Programming in Perl.

just in addition to the others' constructors:

sub new {
  my $class = shift; $class = ref $class || $class;
  # other stuff
  bless $self,$class;
}

It allows you to use the constructor as an instance method. This is also described in perltoot and imho very usefull.

    just to give you all the info, there are some people who do not think that the 

    my $class = shift; $class = ref $class || $class;

    construction is useful or appropriate in a constructor. I'm just getting into this OOP stuff myself, and have avoided that particular method mostly because of posts by tilly and merlyn. Tilly uses some examples you might like in A Cat's eye view of OO (though all of the thread might be helpful) and even refers to merlyn's take on the matter, ref($proto) - just say no!. and of course, there are excellent resources in the tutorials section, specifically the Perl Object Oriented Meta-Tutorial , which is basically a list of further resources.

    good luck with the OOP in perl, from someone who's also in the middle of struggling with it!
