At my work we use perl extensively for utility scripts and such. In the past few years there has been a push to write new scripts in python, but I don't really see the point. It has most of the same drawbacks that perl has: 30x slower than a compiled language and dynamic typing.

We have many scripts that range from 5.8 to 5.36 and everything in between. 5.8 is 20 years old. Someone did a search & replace on the shebang lines to move all the older ones to 5.20 (why they picked that one, I don't know) and everything just continued to work.

I prefer perl over python. turn on use strict, use warnings FATAL => 'all' and use modern function signatures. Perl is still great for its purpose.
