Of course it doesn't.  You can't set the length of an AA:
- you can't use it to add elements, because an AA element cannot exist without a key
- you can't use it to remove elements, as how would it know which to remove?

Works for me (DMD 1.009, Win98SE).  Which version and OS are causing a problem for you?
