If you'd just stop saying things that can't be backed up, I wouldn't
have to keep responding.

Where is your proof that mod_perl is "slower than most any j2ee
application"?

I'm still waiting for "Java does things better" to be demonstrated.

Perl is a hybrid OO language, just like Java.  Now if you compare both
of them to Smalltalk, I see your point.  But Java has primitive types
that cannot be subclassed or extended, just like Perl.  There's really
no difference.  Perhaps you've not read "Object Oriented Perl" by
Damian Conway, to see just how rich Perl's object model is, even
compared to Java and others.

Perl is no more interpreted than Java.  Perl's compiler translates the
entire program down to bytecodes, and the bytecodes are then executed
by the Perl Virtual Machine, just like Java.  (I won't bring up any
benchmarks here... it's unfair to Java. :)

See... it's the nonsense you keep spouting that makes me want to slap
you silly.  Get a clue.  Perl is a serious, mission-critical language,
being actively developed by hundreds of people who depend on it to
remain stable, fast, and useful.

I've seen both.  Java has its place.  Perl has its place.  Stop
dissing Perl, because you are apparently unaware of what is actually
going on.  I guess that would make you a language bigot.

And many "enterprise applications" are completely in Perl.
cbs.sportsline.com is 90% Perl.  Etoys.com was 100% Perl.  imdb.com is
100% perl.  valueclick.com is 100% Perl.  Amazon.com does all their
backend processing in Perl.  Boeing uses Perl in every step of their
cad/cam process... every number defining the 777 airplane was passed
through Perl.

You smell a bit like that now though, mostly through your ignorance of
Perl.  Maybe you're not "unfounded pro Java", but you are "unfounded
anti Perl".  And I won't allow that here.  I'll certainly permit Perl
to lose on its technical merits, but I won't let Perl lose through
your ignorance of what it actually can be or do.
