+L</like> and L</unlike> don't special case regular expressions that are passed as C<'/.../'> strings.
+A string regexp argument is always treated as a the source of the regexp, making C<like $text, $rx> and C<like $text, qr[$rx]> equivalent to each other and to C<cmp_ok $text, '=~', $rx> (and likewise for C<unlike>).

 L</cmp_ok> throws an exception if the given operator isn't a valid Perl binary operator (except C<'='> and variants).
 It also tests in scalar context, so C<'..'> will be treated as the flip-flop operator and not the range operator.

+L</is_deeply> doesn't guard for memory cycles.
+If the two first arguments present parallel memory cycles, the test may result in an infinite loop.

+The tests don't output any kind of default diagnostic in case of failure ; the rationale being that if you have a large number of tests and a lot of them are failing, then you don't want to be flooded by diagnostics.
