There is nothing extant better than Perl for regex. Nothing.
That may have been true 15 years ago, but it's blatantly false today. I have a client with a legacy Perl text processing job that was beginning to run too slowly to keep up (log processing was starting to take longer than the log files were generated). They were going to buy an expensive log analysis tool, so I asked them if they actually wanted the tool or if they were happy with the output of their Perl script. They preferred the output of the script. So I said, "Give me a few hours."
A few hours later, I had translated the Perl script, line-by-line, into (I shit you not) Java. Ran two orders of magnitude faster. In Java.
Yes, slashdot's favorite whipping boy of a language bested Perl by two orders of magnitude.
