Let's face realityThe top 20 popular programming languages in the world
(according yo TIOBE index), all except SQL, Assembly and perhaps Matlab have
built in Regex capability which is in most cases similar if not identical to
Perl/PCRE, and as powerfull.AWK is number 42. Rexx is somewhere between 51 and
100 (and this is after I pleaded with TIOBE to include it.)If we want to
somehow raise Rexx to the top 50, then trust me on that, using Posix ERE would
be less than satisfactory.

I'd be reasonably satisfied with POSIX ERE and back-references optionally
assigned to Rexx variables.
