Including aeson, which I think we'd all very much like to do, requires dlist-0.5. Now, dlist has been around for a very long time, and is very stable. I do not believe that dlist's API is exposed indirectly via aeson at all.
I hereby propose that it be added to the platform. At the very least, it could be like primitive - in the platform, but not "part" of it.
Thoughts?
+1 However, note that I don't mind dropping the dlist dependency from aeson. I use it in a very limited internal place: https://github.com/bos/aeson/blob/master/Data/Aeson/Types/Generic.hs#L213 Don, If we do decide to include dlist in the HP it would be great if the following instances can be added to it: instance Alternative DList where empty = empty (<|>) = append instance Eq a => Eq (DList a) where (==) = (==) `on` toList instance Ord a => Ord (DList a) where compare = compare `on` toList instance Show a => Show (DList a) where showsPrec p dl = showParen (p >= 10) $ showString "Data.DList.fromList " . shows (toList dl) Bas
