need to redispatch or return any specific value.

+=head2 does $role_name
+
+This will check if the invocant's class "does" a given C<$role_name>.
+This is similar to "isa" for object, but it checks the roles instead.

+From the Moose POD:
+
+ C'mon, how many times have you written the following code while debugging:
+
+ use Data::Dumper;
+ warn Dumper $obj;
+
+ It can get seriously annoying, so why not just use this.
+
+The implementation was lifted directly from Moose::Object.
