Blog post where someone used Python quirks to evaluate false == true (lemmy.dbzer0.com)

Does anyone remember an old blog post where someone used various Python language hacks to override boolean primitives, such that the statement false == true evaluated as true? I'm 90% sure it was python, but maybe it was some other language.

I've been looking for that post recently, but haven't had any luck.

Thanks to antagonistic for finding it! I guess it was less of an "exploit", and more of a "please don't touch the loaded foot-gun"

True is False gives false in Python 2.7.18 as well as 3.x. But, in 2.x, they aren't keywords, so you can say True=False=5 and then they are both the same object.

I really need to stop trusting how durable this language is.
