The lens documentation in src/Snap/Snaplet.hs needs to be updated for the new lens library. This needs to be done before the 0.10 release.
Also please think about limiting amount of Control.Lens exported from Snap.
edwardk suggested exporting only Control.Lens.Loupe, but I think some common things like set, over, view should also be exported. Exporting whole thing pollutes namespace.
P.S. I don't understand lens enough to write docs.
Ok, I changed to only export Control.Lens.Loupe. Docs still need to be updated.
I've tried to update docs, but failed to explain lens simply, because Lens type is not simple, and SnapletLens don't really get generated by makeLenses. sopvop/snap@72a8e4e Ideas, anyone?
