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”

    Maybe they did “False is True” because they’re both the same Python object?

        Maybe they defined them as variable names instead?

        Or they could have just changed the language. Do you remember them compiling or editing C? (Python is usually run on cpython)

          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.
