 It is important to note that these are virtual members, not virtual methods
 of object-orientated programming, and can be of any type.
-However, since \CFA has function pointers and they are allowed, virtual
-members can be used to mimic virtual methods.
+\CFA still supports virtual methods as a special case of virtual members.
+Function pointers that take a pointer to the virtual type will be modified
+with each level of inheritance so that refers to the new type.
+This means an object can always be passed to a function in its virtual table
+as if it were a method.
 
 Each virtual type has a unique id.
