    33In this ticket, there is a method which determine the signature of a metric. So it is no more necessary to give the signature of your metric while declaring, Sage is able to compute it! Therefore Sage would give the truth class of the declaring metric: Riemannian metric or Lorentzian metric or pseudo-Riemannian metric or degenerate metric.
