    In the same vein, the post tactic should also simplify

    dom(∅) to ∅
    ran(∅) to ∅

    etc. (there are surely many more similar simplifications.)

    The following rules has been added to the Simplification Rewriter:
    r[∅] = ∅
    dom(∅) = ∅
    ran(∅) = ∅
    The User Manual has been updated.
    This is available in the CVS.
    Cheers,

    Added rule ∅[A] == ∅ to the AutoRewriter, as proposed by Son in exploratory project _exploratory/tshoang/org.eventb.contributer.seqprover.fr1798741.
