Ah, so is the idea, then, to use *op()* when `n` wasn't actually
constructed formally, but rather assembled by the user, so as to match
the type of the accessor function normally supplied as the argument to the
constructor?

Hi All,
Referring to the following, which is taken from the *Control.Newtype

op ::

o = (o - n) - n -

The phantom parameter solves the same problem as scoped type variables.
Granted, if you find yourself in that kind of polymorphic soup you have
deeper problems...
