Returns an appropriate type for creating mutable copies of its argument.
The type-for-copy value of a collection must be an instantiable subtype of <mutable-collection>. For collections that are themselves mutable, the collection’s actual class is generally the most appropriate (assuming it is instantiable). The type-for-copy value for a sequence should be a subtype of <sequence>, and the type-for-copy value of an explicit key collection should be a subtype of <explicit-key-collection>.
The method on <object> returns the result of calling object-class on the object.
