On points 1 & 2:
1. Perl supports more programming paradigms than Java.
2. You write fewer lines of perl to get things done than you do in Java.

There is empirical evidence of this - anyone seen the Software Productivity
Group research on programming languages? In general:

C - 6 x more productive than assembler
Java/C++ - 3 x more productive than C
Perl/Python (Ruby/javascript not represented) - 2-3 x more productive than
Java/C++

Results are consistent over 2 studies a decade or so apart.

Point 3 does scream "Java" but take a look at this:

http://lambda-the-ultimate.org/node/2941

The author laments the ubiquity of Java as the language of choice in
education (despite having advocated it himself). On balance he'd go for
python but doesn't dismiss Perl out of hand either.

I can't convince my own colleagues of the benefits of perl despite the fact
I continually produce decent quality s/w faster than they can, when given
the opportunity. Folk will see what they expect to see.

This was demonstrated by a psychology experiment in the 90's. Subjects were
asked to look at a video of 2 football teams passing a football around and
count how many times the ball was passed.

When asked at the end of the video the answers were pretty accurate. Then
they were asked "What about the gorilla?". In the middle of the video
someone in a gorilla suit walks on, bangs on its chest and walks off. Hardly
anyone spots the gorilla.
