quantified, but not if they are being used as conditions, so the above pattern
is faulted by Perl. PCRE2 has now been changed so that it also rejects such
patterns.

+
+1. Serialization and de-serialization functions have been added to the API,
+making it possible to save and restore sets of compiled patterns, though
