Can anyone advocate here their thoughts to "must use" Perl for any scripts / projects?
It is also great at stability (ie. code written 20+ years ago, still works on modern systems).
So for me, something that I'll write, put in some cron somewhere and forget, is all written in perl... at the same time, my colleagues are rewriting old python2 stuff, because modern distros come with python3 only. Some of them had to fix stuff even for 2.6->2.7 python versions.
On the flip side, I would never get a Perl script and rewrite it in Bash.
Perl <3
The coloring of strings as dirty or clean on I/O.
The object model of Moose.
In general, Perl tends to be much faster than the competing scripting languages (which is why you never see people talk about benchmark numbers, they'd give you the wrong answer).
