        muxpack [selection]

    ::

        This pass converts cascaded chains of $pmux cells (e.g. those create from case
        constructs) and $mux cells (e.g. those created by if-else constructs) into
        $pmux cells.

        This optimisation is conservative --- it will only pack $mux or $pmux cells
        whose select lines are driven by '$eq' cells with other such cells if it can be
        certain that their select inputs are mutually exclusive.
