-Moose - A postmodern object system for Perl 5

=head1 SYNOPSIS
package Point;
Moose is an extension of the Perl 5 object system.
The main goal of Moose is to make Perl 5 Object Oriented programming
-easier, more consistent and less tedious. With Moose you can to think
+easier, more consistent, and less tedious. With Moose you can think
more about what you want to do and less about the mechanics of OOP.
Additionally, Moose is built on top of L<Class::MOP>, which is a
class construction/definition, but still stay out of your way if you want it
to. Here are a few items to note when building classes with Moose.
-Unless specified with C<extends>, any class which uses Moose will
-inherit from L<Moose::Object>.
+When you C<use Moose>, Moose will set the class's parent class to
+L<Moose::Object>, I<unless> the class using Moose already has a parent
+class. In addition, specifying a parent with C<extends> will change the parent
+class.
Moose will also manage all attributes (including inherited ones) that are
defined with C<has>. And (assuming you call C<new>, which is inherited from
=item I<coerce =E<gt> (1|0)>
This will attempt to use coercion with the supplied type constraint to change

-a type constraint in order for this to work. See L<Moose::Cookbook::Basics::Recipe5>
-for an example.

+constraint, and that type constraint B<must> define a coercion. See
+L<Moose::Cookbook::Basics::Recipe5> for an example.
=item I<does =E<gt> $role_name>
The I<trigger> option is a CODE reference which will be called after
the value of the attribute is set. The CODE ref is passed the
-instance itself, the updated value, and the original value if the

attribute was already set.
You B<can> have a trigger on a read-only attribute.

With the duck type option, you pass a duck type object whose "interface" then

list of methods passed to C<duck_type> to create a duck type object. For more
information on C<duck_type> please check
L<Moose::Util::TypeConstraints>.
This tells the class to use a custom attribute metaclass for this particular
attribute. Custom attribute metaclasses are useful for extending the
capabilities of the I<has> keyword: they are the simplest way to extend the MOP,
-but they are still a fairly advanced topic and too much to cover here, see

obtain the value used to initialize the attribute. See the L<builder

the development of both modules and is highly recommended.
