NAME

       namespace::autoclean - Keep imports out of your namespace

SYNOPSIS

	   package Foo;
	   use namespace::autoclean;
	   use Some::Package qw/imported_function/;

	   sub bar { imported_function('stuff') }

	   # later on:
	   Foo->bar;		   # works
	   Foo->imported_function; # will fail. imported_function got cleaned after compilation

DESCRIPTION

       When you import a function into a Perl package, it will naturally also be available as a method.

       The "namespace::autoclean" pragma will remove all imported symbols at the end of the current package's compile cycle. Functions called in
       the package itself will still be bound by their name, but they won't show up as methods on your class or instances.

       This module is very similar to namespace::clean, except it will clean all imported functions, no matter if you imported them before or
       after you "use"d the pragma. It will also not touch anything that looks like a method, according to "Class::MOP::Class::get_method_list".

       If you're writing an exporter and you want to clean up after yourself (and your peers), you can use the "-cleanee" switch to specify what
       package to clean:

	 package My::MooseX::namespace::autoclean;
	 use strict;

	 use namespace::autoclean (); # no cleanup, just load

	 sub import {
	     namespace::autoclean->import(
	       -cleanee => scalar(caller),
	     );
	 }

PARAMETERS

   -also => [ ITEM | REGEX | SUB, .. ]
   -also => ITEM
   -also => REGEX
   -also => SUB
       Sometimes you don't want to clean imports only, but also helper functions you're using in your methods. The "-also" switch can be used to
       declare a list of functions that should be removed additional to any imports:

	   use namespace::autoclean -also => ['some_function', 'another_function'];

       If only one function needs to be additionally cleaned the "-also" switch also accepts a plain string:

	   use namespace::autoclean -also => 'some_function';

       In some situations, you may wish for a more powerful cleaning solution.

       The "-also" switch can take a Regex or a CodeRef to match against local function names to clean.

	   use namespace::autoclean -also => qr/^_/

	   use namespace::autoclean -also => sub { $_ =~ m{^_} };

	   use namespace::autoclean -also => [qr/^_/ , qr/^hidden_/ ];

	   use namespace::autoclean -also => [sub { $_ =~ m/^_/ or $_ =~ m/^hidden/ }, sub { uc($_) == $_ } ];
