As Dave has analysed: the dictionary falls back to the current implementation.
So wrt. your question "Is it still able to find the value?", the answer is
Yes, certainly. It's fully backwackwards compatible, with the limitation
in msg152030 (i.e. the dictionary order may change for dictionaries with
string keys colliding in their hash() values).
