+=item C<call_sub_if $name, $check, @args>
+
+Calls the sub C<$name> on C<$self> with the arguments C<@args> if
+C<$check> is trueish. If C<$check> is a code reference then it will be
+called with C<$self> as the only argument and its result determines
+whether or not C<$name> is called.
+
+Returns the sub's result if the check is positive and C<$self>
+otherwise.
+
+=item C<get_first_conflicting @attributes>
+
+Returns the first object for which all properties listed in
+C<@attributes> equal those in C<$self> but which is not C<$self>. Can
+be used to check whether or not an object's columns are unique before
+saving or during validation.
