In the scoped addresss architecture draft, we say:

   The IPv6 unicast loopback address, ::1, is treated as having link-
   local scope within an imaginary link to which a virtual "loopback 
   interface" is attached. 

effectively saying that the ::1 loopback address is a special-case
link-local address.
