I took the time to update the MonadFail wiki page to include both the
timeline currently under consideration, lengthening the timeline to finish
in 8.8 to comply with the "3 release policy" and to ensure that folks
always have a notification of pending breaking changes.
I included a couple of personal comments about the desugaring in 1.3 where
we could do better. The improvements in 1.3 could be made any time over the
8.0 and 8.2 releases before we start expecting people to cut over in 8.4
As for the "mob", please keep in mind that the vast majority of feedback
about the MonadFail proposal has been positive and draw heart from that.
Many of the folks who were against the Foldable/Traversable generalizations
(e.g. Lennart) are heavily in favor of MFP.
