I didn't mean wrap, as in subclass, I meant wrap in the sense of having
ndarray as a private component in a class. One could maybe make a class
factory that made a wholly new class for every freshly instanced monitor
object and access info could be kept in class variables. Every instance of
the generated class would essentially be a view of a single ndarray

I don't think all possible accesses could be caught, but for the purposes of
mc something less perfect would probably serve.
