Hmm, my personal feeling is that if you use Memoize and see a dramatic performance boost when using recursive functions like this, then you really need to rethink your algorithm as there is very likely a much better solution

(To be fair, I suspect this is not always true, however it is absolutely worth investigating, especially if the trade off in memory utilisation is particularly expensive)
