propably yes. But we should bear in mind that addresses of different
scopes are not comparable with each other in the sense of apples vs.


  select 'fe80::1%em0'::inet = 'fe80::1%em1'::inet;

should return null.

Also how do we define sort order if not all values are comparable.

Not sure what that would buy us.  Stripping the scope from the address
does not seem the right thing to do.

Extending the generic inet type with scoped addresss is another question.
