       Moose exports a number of sugar functions in order to emulate Perl built-in keywords. These can cause
       clashes with other user-defined functions. This document provides a list of those keywords for easy
       reference.

   The'meta'keyword
       "use Moose" adds a method called "meta" to your class. If this conflicts with a method or function you
       are using, you can rename it, or prevent it from being installed entirely. To do this, pass the
       "-meta_name" option when you "use Moose". For instance:

         # install it under a different name
         use Moose -meta_name => 'moose_meta';

         # don't install it at all
         use Moose -meta_name => undef;

   MooseKeywords
       If you are using Moose or Moose::Role it is best to avoid these keywords:

       extends
       with
       has
       before
       after
       around
       super
       override
       inner
       augment
       confess
       blessed
       meta

   Moose::Util::TypeConstraintsKeywords
       If you are using Moose::Util::TypeConstraints it is best to avoid these keywords:

       type
       subtype
       class_type
       role_type
       maybe_type
       duck_type
       as
       where
       message
       inline_as
       coerce
       from
       via
       enum
       find_type_constraint
       register_type_constraint

   AvoidingcollisionsTurningoffMoose

       To remove the sugar functions Moose exports, just add "no Moose" at the bottom of your code:

         package Thing;
         use Moose;

         # code here

         no Moose;

       This  will  unexport  the  sugar  functions  that  Moose originally exported. The same will also work for
       Moose::Role and Moose::Util::TypeConstraints.

       Sub::Exporterfeatures

       Moose, Moose::Role and Moose::Util::TypeConstraints all use Sub::Exporter to handle all  their  exporting
       needs. This means that all the features that Sub::Exporter provides are also available to them.

       For instance, with Sub::Exporter you can rename keywords, like so:

         package LOL::Cat;
         use Moose 'has' => { -as => 'i_can_haz' };

         i_can_haz 'cheeseburger' => (
             is      => 'rw',
             trigger => sub { print "NOM NOM" }
         );

         LOL::Cat->new->cheeseburger('KTHNXBYE');

       See the Sub::Exporter docs for more information.

       namespace::autocleanandnamespace::clean

       You  can  also  use  namespace::autoclean  to  clean  up  your  namespace.  This will remove all imported
       functions from your namespace. Note that if you are importing functions that are intended to be  used  as
       methods (this includes overload, due to internal implementation details), it will remove these as well.

       Another  option  is  to  use namespace::clean directly, but you must be careful not to remove "meta" when
       doing so:

         package Foo;
         use Moose;
         use namespace::clean -except => 'meta';
         # ...
