I am happy you found a solution, but I fear that adding decorators and
assertions will not do what you are asking for. I missed the
original question, but it looks to me as if what you were looking
for is a nice python dictionary with a tuple as an index. Since
tuples are immutable, they can be used as indices, while arrays
cannot.
Or, despite finding it interesting, have I misunderstood what
you are doing altogether?
