(1) That Python depends on indentation destroyed when Sultan-theme gets its hands on it is not in dispute:

Here is some C code I posted recently

That function lacked a main() for test purposes, so I’ve appended one at the bottom, already sultanized.

Sultanize, copy-paste, compile, and type ‘a.out 23.14069263’ to verify that _this_ code can withstand Sultan’s destructive efforts.

(2) I haven’t a clue what your point is. But with approximately 99% of the world’s writing now transcripts from inportant intellectuals like Alex Jones, and gibberish from social media, I don’t think future conspiracists will have lack source material!
