So I just read through perlre and I couldn't find something: how does one include a (code-based) conditional expression in a regex, analogous to actions in P::RD? Is it even possible? If so, then one could not only find the last match (which may differ slightly from reversing the result of a reversed regex):

"abcdef" =~ /(..*..*.)(?{$last = $^N})(?!)/;
print "[$last]\n";  ## "[def]"

but also the (say) tenth match.

Another solution to my problem would be possible if P::RD had non-greedy matches. Is it likely that this will be implemented soon? I guess I could try hacking on it myself.

P.S.: Has anyone ever used customre? Super Search gave back only one result ...
