the file name should probably include ReadingList, or the class name should not
contain it.

[gambard, 2017/04/05 12:24:43]

The idea is to have a file defining all the extra information needed (for
Reading List, Bookmarks...). If you think we should have one extra per file I
can rename this one.

[Olivier, 2017/04/05 13:07:23]

So may be add _builders to the file name? or something similar?

[gambard, 2017/04/06 09:28:50]

Done.

++ (ContentSuggestionReadingListExtra*)extraWithStatus:

[Olivier, 2017/04/05 13:45:22]

reading list status is read/unread.
ExtraWithDistillationStatus?

[gambard, 2017/04/06 09:28:50]

Done.

+    (ReadingListUIDistillationStatus)status;
+
+// Status of the distillation.
+@property(nonatomic, assign) ReadingListUIDistillationStatus status;

[Olivier, 2017/04/05 11:58:11]

Why not ReadingListSuggestionExtra::ReadingListSuggestionDistilledState?

[gambard, 2017/04/05 12:24:43]

Because ReadingListSuggestionExtra::ReadingListSuggestionDistilledState is in
components and the components files cannot be include from the UI layer (i.e.
this file).

[Olivier, 2017/04/05 13:07:23]

Why?
Is there a circular dependency?

[Olivier, 2017/04/05 13:45:22]

Ack, discussed offline.
