While the constructs are higher level, the compiler still needs to deal with all of this complexity. Normal developers can ignore this. But there will be a memory model and a modern language should specify this. If swift does not have an equivalent idea of what its memory model should be, the ARM/X86 splits will lead to interesting bugs.
