Whatever you do, don't get in a time machine back to 1998 and become a Unix sysadmin.

(Though we didn't have CL-PPCRE then. It's really the best thing that ever happened to regex.)

I have to admit that using CL-PPCRE does not really help me understanding the regexp any better. But this may be because I deal with complex regexps for decades now, and I just read them.

I was a sysadmin with some Linux usage in 1998, does that count?
