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

VERSION
    version 2.2200

SYNOPSIS
      package MyApp::Mooseish;

      use Moose::Exporter;

      Moose::Exporter->setup_import_methods(
          with_meta       => ['has_table'],
          class_metaroles => {
              class => ['MyApp::Meta::Class::Trait::HasTable'],
          },
      );

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

      package MyApp::Meta::Class::Trait::HasTable;
      use Moose::Role;

      has table => (
          is  => 'rw',
          isa => 'Str',
      );

DESCRIPTION
    This recipe expands on the use of Moose::Exporter we saw in
    Moose::Cookbook::Extending::ExtensionOverview and the class metaclass trait we saw in
    Moose::Cookbook::Meta::Table_MetaclassTrait. In this example we provide our own metaclass trait,
    and we also export a "has_table" sugar function.

    The "with_meta" parameter specifies a list of functions that should be wrapped before exporting.
    The wrapper simply ensures that the importing package's appropriate metaclass object is the
    first argument to the function, so we can do "my $meta = shift;".

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

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 namespace::autoclean;

      use Moose;
      use MyApp::Mooseish;

      has_table 'User';

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

      sub login { ... }

CONCLUSION
    Providing sugar functions can make your extension look much more Moose-ish. See Fey::ORM for a
    more extensive example.
