For those, like me, who get excited by this note that there are restrictions on the Unicode categories that are allowed, see the supported characters¹ and gory details². It is often enough to write math-y code in a usable way, but occasionally you'll find you can't use the character you want.

That would be quite unpythonic. Down that road lies Raku.

EDIT: To be clear, I like Raku. But Python has its own distinct aesthetic.

Well you can't do `l = lambda` to replace it either, it's not really anything to do with allowing full unicode identifiers.

I'm surprised that you're surprised.
