Query: Hankel Pfaffians, Discriminants and Kazhdan-Lusztig bases   We use Kazhdan-Lusztig bases of representations of the symmetric group to
express Pfaffians with entries $(a_i-a_j) h_{i+j}$. In the case where the
parameters $a_i$ are specialized to successive powers of $q$, and the $h_i$ are
complete functions, we obtain the $q$-discriminant.
