If it can allow storing any kind of key, like a Map, and it's just the initial data you're referring to, then maybe it is a Map. As long as the contract that `map.set(x, y); map.get(x) === y` works for any `x` and `y`, then you're probably fine.

It's a string-keyed map, but that just means that you toString
everything, as Anne says.  Your contract is still maintained, assuming
a non-degenerate toString.
