According to the docs: / Particular keys in an associative array can be removed with the remove function:/ This says the key is removed, but says nothing about the value. Assuming the value is a class reference or a pointer, is it still referenced internally by the aa after the remove call or not? I don't want to leave any dangling references hanging around, so I need to know if we should be doing something like this: aa[key] = null; aa.remove(key); If the value *is* no longer referenced, then perhaps the docs should be updated to read: / Particular key-value pairs in an associative array can be removed with the remove function:/

I would assume the value is as well. It wouldn't make much sense for the key to be deleted and the value left, as they are in the same struct. I think the reference of "key" in the docs in this case refers to the "key-value pair" as you've pointed out.

to. But no matter how senseless it would seem, and no matter how much I assume, the docs still say 'key' and not 'key-value pair'. I've been burned by little things like this before (not in D!), so just want it clarified.
