The alternative would be nasty - let's break out a protracted set of functions, variables, loops, etc to process this piece of text in a more "readble" way? No thanks - let me bang-out the regexp and be done.
Also - At least Perl uses a normal open/close (braces) to begin and end a scope - unlike Python - which relies on the number of leading spaces. (I've been using Python for years - can handle that - but still think it's a very bad idea).
For me - Pearl's biggest downside has been that the world has simply gone to Python largely, and so have I.Whereas I used to love Perl, I find it hard to keep switching back-and-forth.
That being said - I miss the ease at which Perl can fork a subproces, then scrape and parse it's output. Yes you can do this with Python - but it does take more keystrokes. From a linguistics point of view - it comes down to Information Density. Thus, we can argue that Python looks cleaner, but Perl's code is denser.
What would I do with a device that output 2kWs and lasted 2 or 3 hours???
There have been a lot of people (too many references to site) who do things like make FM transmitters out of a Raspberry PI.
I used to play with making my Apple ][+ do wonky things to transmit weird noise to my FM radio back in the day...
