Well unfortunately isAssociativeArray from std.traits fails on your
hashes (reasonable, since it calls __traits internally and has no way
of knowing about external hashes).

I also can't use your hashes with some helper functions that I use:

template ValueType(V : V[K], K) {
    alias V ValueType;
}

The function that needs the above is:

void addKey(AA, Key)(ref AA hash, Key key)
  if (isAssociativeArray!AA && is(KeyType!AA == Key))
{
    hash[key] = (ValueType!AA).init;
}

I can temporarily remove those constraints, but how do I extract the
value type of your hash?
