required C<foo> method, and **NOT** overriding C<foo>. This is an
important distinction to make.
+Now here is another example of a (correct) type of overriding, this
+time using the I<excludes> option.
+
+ package Role::Foo;
+ use Moose::Role;
+
+ sub foo { ... }
+
+ package Role::FooBar;
+ use Moose::Role;
+
+ with 'Role::Foo' => { excludes => 'foo' };
+
+ sub foo { ... }
+ sub bar { ... }
+
+By specifically excluding the C<foo> method during composition,
+we allow B<Role::FooBar> to define it's own version of C<foo>.
