    I have no problem with text about continuous assignments that continues with
    "including implicit continuous assignments for port and terminal connections."

    I would have a problem specifying execution for port connections separately
    from continuous assignments. This would be nonsense for port connections
    that do not use implicit continuous assignments, such as collapsed ports.

    >Besides, inouts are different.

    Inouts are never continuous assignments, and can never be connected to
    a constant or a 2-state variable. By only specifying evaluation for port
    connections that are continuous assignments, they are excluded, as they
    should be.

    >And I am not completely sure about the equivalence to continuous assignments,
    >as they ignore strength.

    When an input or output port is not equivalent to a continuous assignment,
    it is because it collapsed. In that case, it is nonsense to talk about
    evaluating it. The cases where they need to be evaluated are all continuous
    assignments.
