Okay, thanks Carlos.  I'll have to run the simplified test case, but for Walnut, I couldn't use a Value[char[]] in any of the ways described (Value is a struct).  I could declare the associative arrays and handle them, but not populate the associative array with anything or set the length.

I thought associative arrays might not be dynamic because it was giving me an Array out of bounds exception when I tried to assign to it.

Regarding the opIndex, what I meant was perhaps being able to, for example, define an override for line two of:

1 ||  int[char[]] x;
2 || x["hello"] = 0;

It's not clear in documentation whether you can or not, only that you can do it with int's - one would assume in static or dynamic arrays.
