=head1 NAME

Moose::Cookbook::Extending::Recipe4 - Acting like Moose.pm and providing sugar Moose-style

=head1 SYNOPSIS

  package MyApp::Mooseish;

  use strict;
  use warnings;

  use Moose ();
  use Moose::Exporter;

  Moose::Exporter->setup_import_methods(
      with_caller => ['has_table'],
      also        => 'Moose',
  );

  sub init_meta {
      shift;
      Moose->init_meta( @_, metaclass => 'MyApp::Meta::Class' );
  }

  sub has_table {
      my $caller = shift;
      $caller->meta()->table(shift);
  }

=head1 DESCRIPTION

This recipe expands on the use of L<Moose::Exporter> we saw in
L<Moose::Cookbook::Extending::Recipe1>. Instead of providing our own
object base class, we provide our own metaclass class, and we also
export a sugar subroutine C<has_table()>.

Given the above code, you can now replace all instances of C<use
Moose> with C<use MyApp::Mooseish>. Similarly, C<no Moose> is now
replaced with C<no MyApp::Mooseish>.

The C<with_caller> parameter specifies a list of functions that should
be wrapped before exporting. The wrapper simply ensures that the
importing package name is the first argument to the function, so we
can do C<S<my $caller = shift;>>.

See the L<Moose::Exporter> docs for more details on its API.

=head1 USING MyApp::Mooseish

The purpose of all this code is to provide a Moose-like
interface. Here's what it would look like in actual use:

  package MyApp::User;

  use MyApp::Mooseish;

  has_table 'User';

  has 'username' => ( is => 'ro' );
  has 'password' => ( is => 'ro' );

  sub login { ... }

  no MyApp::Mooseish;

All of the normal Moose sugar (C<has()>, C<with()>, etc) is available
when you C<use MyApp::Mooseish>.
