By this logic, Bash is a "polyglot task runner" too. With a shebang and executable permissions, I can run `./task1.py` or `./task2.js` or `./task3.sh`. I can also run inline tasks in various languages within a Bash script by piping the source into the appropriate interpreter.

I like and use `just`, but I think the project author's claims around it being "polyglot" are misusing the term.
