Well, you could save one process creation by writing

Shells were somewhat less powerful in those days. I would describe the

expressions. And I guess combining that with more sophisticated data-

Perl is more awk+sed+sh in a single language. Basically the killer

Perl is a high-level programming language with a rich syntax??, with
support for deterministic automatic memory management, functions as
first-class objects and message-based OO. It's also a virtual machine
for executing threaded code and a(n optimizing) compiler for translating
Perl code into the corresponding threaded code.
 
Its syntax is also a horrific mess. Larry took the worst parts of C and shell
syntax and mashed them together. Its no surprise Perl has been ditched in
favour of Python just about everywhere for new scripting projects. And while
I hate Pythons meangingful whitespace nonsense, I'd use it in preference
to Perl any day.

I think you've identified the one language that Python is better than.
