+=head2 Using Moose in Components
+
+The correct way to use Moose in a component in a both forward and backwards
+compatible way is:
+
+ package TestApp::Controller::Root;
+ use Moose;
+ BEGIN { extends 'Catalyst::Component' }; # Or ::Controller, or whatever
+
+See L<Components which inherit from Moose::Object before Catalyst::Component>.

C<Catalyst::Component> inherits from C<Moose::Object>, and so C< @ISA > fails
to linearize.
-The fix for this is to not inherit directly from C<Moose::Object>
-yourself. Having components which do not inherit their constructor from
-C<Catalyst::Component> is B<unsupported>, and has never been recommended,
-therefore you're on your own if you're using this technique. You'll need
-to detect the version of Catalyst your application is running, and deal
-with it appropriately.
-
-You will also see this issue if you do the following:
-
- package TestApp::Controller::Example;
- use Moose;
- use base 'Catalyst::Controller';
-
-as C< use base > appends to @ISA.

The correct way to use Moose in a component in a both forward and backwards
compatible way is:
Note that the C< extends > declaration needs to occur in a begin block for
L<attributes> to operate correctly.

You also don't get the L<Moose::Object> constructor, and therefore attribute
initialization will not work as normally expected. If you want to use Moose
attributes, then they need to be made lazy to correctly initialize.
If you depend on Catalyst 5.8, then B<all> Moose features work as expected.

Similar to the above, this will also fail:
