    So the real question here, which is the most mystifying language? Perl? or [Brainfuck](https://en.wikipedia.org/wiki/Brainfuck)?! :o

        It's just pointless obfuscation, but its kinda neat. That code prints out "Just another Perl hacker" using only keywords in perl. The trick to it is that the "q" keyword works as a quote, and the rest of the code is just operating on the keywords that are now just strings inside the q tags.

                            It's just the initials of some keywords, from which the output gets built (hex alarm chdir kill exec return --> hacker).

                              I used to do Perl, back when it was all the rage for web development. Fun to write, an absolute nightmare to maintain. You can do just about anything with one line of code, except read it later.

                                Yeah, but it can be really useful too. Back in the 80s I wrote a perl script that took all the list files (Comadore Amiga 68000 assembler) from a project and combine them into a single list file that had the absolute address for all the instructions. The original list files all started at zero so they weren't really very helpful when trying to debug. I use to use perl fairly regularly (I'm retired now) to make support routines for my projects. My per scripts are very C like since, as an embedded engineer, I pretty much did all my programming in C/C++ (at least for the last 25 years or so).

                                          Languages I've used commercially or non-commercially (written at least a few lines of code). C C# C++ Eiffel F# Fortran Go JavaScript PL/SQL Pascal Perl Powershell Python Q# Solidity TypeScript VB VB.NET VBA VBScript Perl is the most unpleasant of the lot, although I admit it's very good at what it does.
