Well, you've demonstrated that memory addresses aren't that hard. But you've also demonstrated how easy it is to get undefined behavior in C programs. C's pointers aren't memory addresses. Ok, they tend to be represented as such at run time, but that's not what the spec actually says the are. And as far as compiler authors are concerned, they can do anything they want as long as it's within spec. Further, the spec even requires some additional behaviors pure memory addresses aren't capable of. See https://www.ralfj.de/blog/2020/12/14/provenance.html https://www.ralfj.de/blog/2020/12/14/provenance.html for examples of the extra requirements. Compared to that mess, lambdas are trivial. They're just functions.
