=item B<has +$name =E<gt> %options>
This is variation on the normal attibute creator C<has> which allows you to
-clone and extend an attribute from a superclass. Here is a quick example:
+clone and extend an attribute from a superclass or from a role. Here is an
+example of the superclass usage:
package Foo;
use Moose;
from its parent class B<Foo>, retaining the C<is =E<gt> 'rw'> and C<isa =E<gt>
'Str'> characteristics, but changing the value in C<default>.
-This feature is restricted somewhat, so as to try and force at least I<some>
-sanity into it. You are only allowed to change the following attributes:
+Here is another example, but within the context of a role:
+
+ package Foo::Role;
+ use Moose::Role;
+
+ has 'message' => (
+ is => 'rw',
+ isa => 'Str',
+ default => 'Hello, I am a Foo'
+ );
+
+ package My::Foo;
+ use Moose;
+
+ with 'Foo::Role';
+
+ has '+message' => (default => 'Hello I am My::Foo');
+
+In this case, we are basically taking the attribute which the role supplied
+and altering it within the bounds of this feature.
+
+Aside from where the attributes come from (one from superclass, the other
+from a role), this feature works exactly the same. This feature is restricted
+somewhat, so as to try and force at least I<some> sanity into it. You are only
+allowed to change the following attributes:
=over 4
You are allowed to B<add> a new C<handles> definition, but you are B<not>
allowed to I<change> one.
