@lolgab @adanskana The fun thing about conventional wisdom is that it becomes more wrong the further it travels from firsthand experience.
Learn #Perl: https://learn.perl.org
@adanskana Perl 6 is boring because it's not Raku, it's some merely evolutionary weirdness.
Learn J.
Then write some macros and primitives to write C in J syntax.
....
Profit.
@adanskana My limited, now a few years old, experience of perl with respect to the exact things I was trying to achieve at the time, is that if you think you can rely on CPAN for things... you might run into "oh, the maintainer of that hasn't updated it in 5+ years and there's nothing but silence in response to any bug reports or enhancement requests. Good luck figuring out the deep Perl voodoo they used in order to fix/enhance it yourself."
This is why I start new projects in Python now. Sure, it has abandoned modules as well, but I've not *yet* had quite the same show-stopper issues.
@adanskana It depends. If it's for fun, or for some concrete opportunity, there can be worse choices. I remember having a lot of fun reading the man pages 20 years ago (»This may seem weird, but that's OK, because it /is/ weird.«).
If it's for resume building or general preparedness, I'd have different ideas.
If you're doing it for fun because you want to learn odd languages, why not Ada?
