I can't stress enough how much I admire that it is true 256 bytes, instead of usual 1k game jams, where submissions are presented as zipped, gzipped, and postfixed, and not including assets to fit the criteria.

Well, you can always include a decompressor in your entry. PNG bootstrap has been popular enough in the JS demoscene for a long time and it starts to be effective for 1K or larger demos. There are other alternatives for smaller sizes, and 256B demos just happen to be too small to put any kind of decompressor in general.

It indeed does not work. I was curious, and found this hilarious article "confirming" its existence: https://www.edureka.co/blog/goto-statement-in-python/ - it's complete nonsense and appears to have been written by ChatGPT.
The feature has been implemented a few times as a joke (more or less), e.g. https://github.com/snoack/python-goto/, but that one at least hasn't been updated for 5 years.
Hats off.
