    >Description:

    A port of an instance array can currently be connected in
    two ways. If the port expression is the same width as the
    port, then each instance port gets connected to the same
    port expression. If the port expression is a vector of
    the same width as the sum of the widths of the ports on
    all of the instances, then each instance gets a part-select
    of the port expression. Any other situation is an error.

    Another capability that would make instance arrays more
    useful is to allow specifying a port expression that is an
    array with the same number of elements as the instance
    array. This would attach one element of the array to each
    instance. Each element would still have to be a legal
    object to connect to the port.

    Unlike issue #55, this does not involve connecting entire
    arrays to a port of any individual instance.

    This connection scheme is sufficiently obvious that some
    users may already assume that it is supported.
