    As a Norwegian, I find it annoying that they “stole” Ø for that purpose. I put a backslash through my zeros instead, so it looks different. I usually pick a coding font with dotted zeros for the same reason.

        Wait, what.

        … oh no. Nope.

        Nope, not going back to set theory, it is 105F / ~40C right now, highly confident I would give myself heat stroke.

        Your comment led me down a bit of a rabbit hole and I found this on Wikipedia:

        When writing in languages such as Danish and Norwegian, where the empty set character may be confused with the alphabetic letter Ø (as when using the symbol in linguistics), the Unicode character U+29B0 ⦰ REVERSED EMPTY SET may be used instead.

        It also mentions what you are alluding to:

        In the past, “0” (the numeral zero) was occasionally used as a symbol for the empty set, but this is now considered to be an improper use of notation.

        And, as a programmer, don’t get me started on nulls…or undefined…or truthyness.
