I always find it interesting when people assume that just because something is out of their awareness is dead…
I learned Perl not too long ago and it is an absolute beast at text processing, a lot less annoying than Python and pip install and cpan seems to have everything in it, implemented multiple times.
The language doesn’t hold your hand at all, doesn’t have tooling like fancy LSP and such, but it is quite usable. With that said, I’d probably hate to use it in a team since you can do the same thing in a dozen different ways!
