The language specification should guarantee that when you implement an algorithm from your algorithm book, you get the same time and space complexity as described in the book, with reasonably small constants. You should be able to hit your big-O target without knowing which "jets" get special treatment by the compiler. That's all I ask for, and it's not too much to ask.
