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);

 same AA.

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
