Depending upon you particular application, 'completeness' may be a more relevant concern than 'performance'. I believe the original Python regex engine did not have all the Perl extensions, some of them decidedly 'non regular'. It was replace by the 'perl-compatible regex engine' (pcre or pre), written in C by a non-pythonista so that other languages/applications, like Python, could drop it in and have what the title claimed -- perl-like re capability. The current sre engine was locally written to include unicode, with the re syntax unchanged (? or nearly so) from the pre. So I would say that the answer to your last question of 'yes'. Terry J.
