It's inadvisable to do this, unless you plan on manually deleting the  
instances.

The reason is because the hash will maintain a pointer to every class  
instance, which means the GC will never collect them.

Also, it's hard to know why you selected that type, but changing  
classInstances to ubyte[][hash_t] should work.

Also, you don't need hash_t, you should be able to do ubyte[][Object]  
classInstances.

then add like:

classInstances[this] = new ubyte[2];

The call to toHash is implicit.
