ButProdclass
Basic “but” rule, which selects a list of plurals minus a list of specifically excepted objects. This can be used to construct more specific production classes for things like “everything but the book” and “all books except the red ones”.
In each grammar rule based on this class, the ‘except_’ property must be set to a suitable noun phrase for the exception list. We’ll resolve this list and remove the objects in it from our main list.
