I'm not sure how array=null will interact with other references to the same AA. 

This should clear them as well (but is more costly).

foreach(k;array.keys)array.delete(k);

AA's are objects, so multiple references to the same AA would result in the data being retained for the references that you did not set to null.

It would be nice to have a .clear function so you could deal with removing all elements when multiple references are used.

void clear(T)(T toClear) {foreach(key; toClear.keys) toClear.remove(key); }

?? O(n) (vs. O(1) for an internal version)

It would be also nice to be able to initialize an AA reference without adding a value to the array.

int[int] a;
int[int] b = a;
a[1] = 2;
auto x = b[1]; // oops
