but you reading is wrong :-)

| Inc() and Dec() are the implicit null

| pointers. The function would be called Inc(*)() as you point out. 
| 
| Hence Inc() and Dec() are temporary objects, not types. The syntax
| "type id(object1, object2)" can't be a function declaration, because
| that would require "type1 id(type2, type3)". Consequently it has to
| be a declaration of id as a type1 object with a constructor taking
| object1 and object2. But there is no such constructor, so there
| should have been an error. 

This is an FAQ.  Have a look at
