Comment(by nthiery):
I should mention: the error appearing in the log comes from the having the
coercion go through
jack polynomials at t=-1; apparently, the scalar product is then non
positive, which causes the error. I have to check the literature. Maybe we
should forbid t=-1, or at least not declare the corresponding broken
coercions.
