I think having actual documentation about how the memory system is supposed to work would do a lot more to answer questions than linking to the tests. For example: x = [1, 2, 3] // is this stack or heap allocated? foo(&x) // how does the compiler know if x needs to be ref counted or not? return &x // is this valid or UB or a compilation error?
