Avoiding collisions

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::Exporter features

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::autoclean and namespace::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';
  # ...
