* _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.
# Implementation
To be done...

* _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.)
