Yes, I could see that, but it doesn't do that with AA's so but I
could see how it could be problematic.
Alternatively, have a keys for a DA:
then one can do
if (y in x.keys)
and this is far more expressive so there is no confusion and also
works with AA's(and would not result in keys having to be created
because it is semantically the same as (y in x) if x is an AA).
