  * _slot_ `-remove` ?_item_ ...?

    This removes the _item_ (or items) from the list of items in the slot. If
    an _item_ is not present in the slot, this does nothing; it is not an
    error to remove a non-present item. If there are no such items in the
    arguments, this does nothing; it is not an error to remove no items.

  * _slot_ `-remove` ?_item_ ...?

    This removes the _item_ (or items) from the list of items in the slot. If
    an _item_ is not present in the slot, this does nothing; it is not an
    error to remove a non-present item. If there are no such items in the
    arguments, this does nothing; it is not an error to remove no items.

To support this, an extra internal operation is added:

  * _slot_ `Resolve` _list_

    This returns the items of _list_ with a resolution operation applied to
    them. The meaning of this operation will depend on the kind of values held
    in a particular slot, but for a slot of classes then the relevant type of
    resolution would be command resolution. (The main slot method
    implementation classes will ensure that this method is always called in a
    context where the resolution context is that of the caller.)
