Exactly my point. People tend to write "quick & dirty" Perl that
*almost*-but-not-quite works for these sorts of tasks, whereas if
you actually handle all the edge conditions the logic of the program
gets quite complex. It isn't just a few dozen lines of Perl any more!

Yes, one can of course process RFC 822 messages "properly" in Perl, but
the code is large enough that personally I'd much rather be using Lisp.
