It is indeed a good and efficient tool, and popular too, but I'm kinda glad it wasn't on the list, because it basically is the point of my tongue-in-cheek comment: choosing the "universal list of tools to solve any problem" is a PERSONAL achievement. It's just basic reality that both Python and PHP are good enough to make things. Some people have one on the list, some another, some may have both. And it's not even true that Haskell cannot be on that list for any sane human. Admittedly, it's not on MY list, but that's just me. Popularity isn't the end of things, nor is it set in stone. Agda or TLA+ aren't very common, but neither are problems they are meant to solve. Neither is Verilog, but it's not even an alternative to anything popular. And Ruby wasn't popular before Rails. Then it was, then it wasn't again. I thought that I was done with Java, but then Android became a thing. I guess you get the point. …I think I'd like if there was only 1 language for everything, but I don't think it's even remotely possible, because then there would be different dialects of that EsperantoPL, different frameworks or ways to use it, and people would never agree on 1 thing anyway.
