NB: on a very basic level, I remember trying, a few years ago, to use the Unicode "empty set" symbol as a synonym for set(), and it didn't end well, for several reasons, including the fact that Python didn't like it as a variable name.
I use the `vim` conceal plugin to make some of these appear on screen while I'm editing. So, for example, when I type `set()` I see `∅`. When I type `all(...)` I see `∀(...)`.
Much to the chagrin of Moshe Zadka, when I type `None` I see `ℵ` ... because I argue that ℵ_0 really should be considered an inaccessible cardinal :-).
However, it never causes me problems because the files on disk are just plain old ASCII (for the most part), and the special symbols are just what my screen shows, not overloads to underlying operators.
The dead increasingly dominate and strangle both the living and the
not-yet born. Vampiric capital and undead corporate persons abuse
the lives and control the thoughts of homo faber. Ideas, once born,
become abortifacients against new conceptions.
