> Even just the distinction between the stack & heap is wrong. They aren't different things, just different functions called on the otherwise identical memory. It's why things like Go work fine, because the stack isn't special. It's just memory.

To add to this: I have seen people who learned C and thought it to be "close to the metal" genuinely believe that stack memory was faster than heap memory. Not just allocation: they thought that stack and heap memory were somehow different kinds of memory with different performances characteristics.

And the C abstract machine maps just fine to computers where the heap and stack are separate, unrelated address spaces, so this isn't even necessarily mistaken reasoning for someone who just knows C.

Separate stack and data memory adress spaces will make the machine incompatible with ISO C due to impossibility to convert between "pointer to void" and "pointer to object". Code address space is allowed to be separate.
