+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.
