=head1 NAME
Moose::Object - The base object for Moose
=head1 DESCRIPTION
This serves as the base object for all Moose classes. Every
effort will be made to ensure that all classes which C<use Moose>
will inherit from this class. It provides a default constructor
and destructor, which run all the BUILD and DEMOLISH methods in
the class tree.
You don't actually I<need> to inherit from this in order to
use Moose though. It is just here to make life easier.
=head1 METHODS
=over 4
=item B<meta>
This will return the metaclass associated with the given class.
=item B<new>
This will create a new instance and call C<BUILDALL>.
=item B<BUILDALL>
This will call every C<BUILD> method in the inheritance hierarchy,
and pass it a hash-ref of the the C<%params> passed to C<new>.
=item B<DEMOLISHALL>
This will call every C<DEMOLISH> method in the inheritance hierarchy.
=item B<does ($role_name)>
This will check if the invocant's class C<does> a given C<$role_name>.
This is similar to C<isa> for object, but it checks the roles instead.
=item B<dump ($maxdepth)>
Cmon, how many times have you written the following code while debugging:
use Data::Dumper;
warn Dumper $obj;
It can get seriously annoying, so why not just use this.
