After the recent attack and the ridicule received at this newsgroup, I think the electrical industry is well advised to stay away from perl and to use more secure packages even if they are much more expensive. Perl is not a viable practical secure solution.
Flash forward to recently, on his new blogspot blog, we see:
This search utility searches a total of 36 files and uses two new PERL scripts. I started writing these programs in September, 2005 and finished on November 2, 2005.There still may be some minor bugs, but it seems to work fine so far.
Well, he can't spell Perl right (yet), but apparently he's all gung-ho about Perl again.
What a difference a few years makes.
