Doesn't help badly-chosen implementations like:

	int fib(int n) {
		if (n <= 2) return 1;
		else return fib(n-2) + fib(n+1);
	}

There's not much the compiler can do to offset programmers choosing the
wrong algorithm for the job. It can't replace educating programmers to
not implement things a certain way unless they have to.
