#Programming languages I've used for building software, either delivering value at my $job, or building utilities for myself:

Awk, Bash, C/C++, C#, Clojure, ColdFusion, Elisp, F#, Flow, Haskell, Java, JavaScript, Kotlin, Pascal, Perl, PHP, Python, Ruby, Scala, TypeScript.

I'm trying to add Rust and OCaml to that list, working my way to “two dozen”. I think I could have stuck to just one or two, though. Just my luck.
