Hello and welcome to the forums!
I have nothing wrong with cross-pollination so long as its adopted by a language’s community as a whole. I also whole-heartedly applaud doing experiments. But I’m otherwise with @Eiji’s here. Coming across business code that someone decided to write in an idiom completely foreign to the language I’m working in is the worst. I’m actually getting a little worked up thinking about the several times this has happened to me 
Is that how it’s ", ".join(["Hello", "World!"]) or something? I’ve heard Pythonistas say this makes more sense (somehow). I honestly don’t know much Python, though!
