Hehe, I checked that out and got an *extreme* deja vu feeling. Which is not
surprising as as that is exactly the same RE syntax as in the module regexp.
Which is also not surprising as regexp is based an AWK which is an old
application from the days before REs became so bloated. It is also very
similar to POSIX ERE.

I would seriously discuss whether we need all the other stuff. Really need
it.
