+=head1 CAVEATS
+
+The uses of the L<indirect> pragma inside the auditted code take precedence over this policy.
+Hence no violations will be reported for indirect method calls that are located inside the lexical scope of C<use indirect> or C<< no indirect hook => ... >>.
+Occurrences of C<no indirect> won't be a problem.
+
+Since the reports generated by L<indirect> are remapped to the corresponding L<PPI::Element> objects, the order in which the violations are returned is different from the order given by L<indirect> : the former is the document order (top to bottom, left to right) while the latter is the optree order (arguments before function calls).
