I see some of the confusion now; as James Knight pointed out, some
people already treat python as binary code, and just run without
reading -- but some people don't.
I do read (or at least skim) other people's code before running it.
If nothing else, I want to see whether it has much chance of solving
my actual problem. By the time I've finished reading it, I have a
fairly good idea what it is doing. That's less true if I can't read
everything, but at least I know which parts to worry about.
Arbitrary unicode identifier opens up the possibility of code that
*looks* like ASCII, but isn't -- so I don't even realize that I missed

I don't mind that he used Sanskrit identifiers; I don't even mind if
he uses Cyrillic identifiers that look like ASCII.
I'll be less likely to use his code, but that is my own problem. If
his code breaks when retyped ... again, that is mostly my own problem.
What I do mind is if he used identifier characters that look like > or
', and I didn't notice because the rest of the code was ASCII, and
python didn't warn me, because, hey, technically, those lookalikes
*are* letters now.
