* Import/export of data constructors in family instances
- Data constructors of a data/newtype family F can be exported and
imported
by writing F(..) or F(ConName).
- This appears the most natural from a user's persepctive - although, it
has a
slightly different flavour than similar import/exports items for closed
data
types. The data constructors denoted by F(..) vary in dependence on
the
visible data instances.
- This has been non-trivial to achieve as RnNames derives its knowledge
of what
sub-binders an F(..) item exports/imports from the relation specified
by
Name.nameParent - ie, the constructors of a data/newtype instance need
to
have the family name (not the internal name of the representation
tycon) as
their parent.
