I fail to see the impossibility of this task. With B you can examine the optree of a given sub and see what it does, its calls, variable accesses, complexity, returns. It would be very easy to see that today_plus_x depended upon variable data from another sub. The classifier would simply examine the calls made and note that today_plus_x calls something not in an explicit list of safe-to-call subs (a time function of some sort) and then throw it out. The problem I face is that simply excluding subs will result in too broad an application of memoization, so I need reasons to include a function in memoization rather than exclude it.
