Fix for this is now pushed to the declarednull branch. It requires an
extra getnode() the first time a tied scalar is assigned after being
declared, and only when both the scalar and the array were declared
uninitialized. So unless one is repeatedly creating/discarding tied
pairs, it shouldn't make much difference.
