NAME
   Homer - Simple prototype-based object system

SYNOPSIS
           use Homer;

           # create a prototype object
           my $person = Homer->new(
                   first_name => 'Generic',
                   last_name => 'Person',
                   say_hi => sub {
                           my $self = shift;
                           print "Hi, my name is ", $self->first_name, ' ', $self->last_name, "\n";
                   }
           );

           # create a new object based on it
           my $homer = $person->extend(
                   first_name => 'Homer',
                   last_name => 'Simpson'
           );

           $homer->say_hi; # prints 'Hi, my name is Homer Simpson'

           # let's extend even more
           my $bart = $homer->extend(
                   first_name => 'Bart',
                   father => sub { print "My father's name is ", $_[0]->prot->first_name, "\n" }
           );

           $bart->say_hi; # prints 'Hi, my name is Bart Simpson'
           $bart->father; # prints "My father's name is Homer"

DESCRIPTION
   "Homer" is a very simple prototype-based object system, similar to
   JavaScript. In a prototype based object system there are no classes.
   Objects are either directly created with some attributes and methods, or
   cloned from existing objects, in which case the object being cloned
   becomes the prototype of the new object. The new object inherits all
   attributes and methods from the prototype. Attributes and methods can be
   overridden, and new ones can be added. The new object can be cloned as
   well, becoming the prototype of yet another new object, thus creating a
   possibly endless chain of prototypes.

   Prototype-based objects can be very powerful and useful in certain
   cases. They can provide a quick way of solving problems. Plus, sometimes
   you just really need an object, but don't need a class. I like to think
   of prototype-based OO versus class-based OO as being similar to
   schema-less database systems versus relational database systems.

   "Homer" is a quick and dirty implementation of such a system in Perl. As
   Perl is a class-based language, this is merely a hack. When an object is
   created, "Homer" creates a specific class just for it behind the scenes.
   When an object is cloned, a new class is created for the clone, with the
   parent object's class pushed to the new one's @ISA variable, thus
   providing inheritance.

   I can't say this implementation is particularly smart or efficient, but
   it gives me what I need and is very lightweight ("Homer" has no non-core
   dependencies). If you need a more robust solution, Class::Prototyped
   might fit your need.

HOMER AT A GLANCE
   *   Prototypes are created by calling "new()" on the "Homer" class with
       a hash, holding attributes and methods:

               my $prototype = Homer->new(
                       attr1 => 'value1',
                       attr2 => 'value2',
                       meth1 => sub { print "meth1" }
               );

               $prototype->attr1; # value1
               $prototype->attr2; # value2
               $prototype->meth1; # prints "meth1"

   *   A list of all pure-attributes of an object (i.e. not methods) can be
       received by calling "attributes()" on the object.

               $prototype->attributes; # ('attr1', 'attr2')

   *   Every object created by Homer can be cloned using "extend( %attrs
       )". The hash can contain new attributes and methods, and can
       override existing ones.

               my $clone = $prototype->extend(
                       attr2 => 'value3',
                       meth2 => sub { print "meth2" }
               );

               $clone->attr1; # value1
               $clone->attr2; # value3
               $clone->meth1; # prints "meth1"
               $clone->meth2; # prints "meth2"

   *   Objects based on a prototype can refer to their prototype using the
       "prot()" method:

               $clone->prot->attr2; # value2

   *   All attributes are read-write:

               $clone->attr1('value4');
               $clone->attr1; # value4
               $clone->prot->attr1; # still value1

   *   New methods can be added to an object after its construction. If the
       object is a prototype of other objects, they will immediately
       receive the new methods too.

               $prototype->add_method('meth3' => sub { print "meth3" });
               $clone->can('meth3'); # true

   *   New attributes can't be added after construction (for now).

   *   Cloned objects can be cloned too, creating a chain of prototypes:

               my $clone2 = $clone->extend;
               my $clone3 = $clone2->extend;
               $clone3->prot->prot->prot; # the original $prototype

CONSTRUCTOR
 new( [ %attrs ] )
   Creates a new prototype object with the provided attributes and methods
   (if any).

CONFIGURATION AND ENVIRONMENT
   "Homer" requires no configuration files or environment variables.

DEPENDENCIES
   None other than Carp.
