Getting the UDAs from inside a symbol must be done via a
recursive procedure in the same manner one would identify the
aforementioned symbol i.e. you have to go through the fields
looking for UDAs *then* use getUDAs.
This is because UDAs cannot convey information without their
context, so the trait doesn't look recursively.
