As much as I'd like to be able to do this, I don't think this can be
done in a backwards compatible way that is guaranteed to do the right
thing in all cases. If the query has one placeholder and the parameter
is a one-element sequence, it is impossible to know for certain whether
the sequence itself or its only contained element should be bound as the
parameter. 

I think we should refuse the temptation to guess and go with the
established semantics.
