Review comment:
The first ``Some(_)`` requires that there be a prefix for the UDF, but that
isn't strictly necessary. I think it should be possible for someone to have the
default namespace of a schema be the same as their udf namespace, in which case
a prefix isn't necessary. I think this can just be ``case (RefQName(_, _, _),
args) =>``
