nil punning?

  Eric Normand explains it better than I could: https://lispcast.com/nil-punning/ https://lispcast.com/nil-punning/ In a nutshell, nil punning is a thing in lisps (and some other languages) where the null value can have different meanings in different contexts. It's comparable to Python's concept of "truthiness" and "falsiness", but more so.

    Oh that, yeah that's what I'm used to from Common Lisp as well.
