This proposal involves a protracted but warranted transition period. In short:
1. `-XNoStarIsType` will be introduced in GHC 8.6
2. Warnings will be introduced in GHC 8.8, increasing in visibility in later releases.
3. `-XStarIsType` will be enabled by default starting 12 releases (roughly 7 years from now) after GHC 8.6.
fine with me so far.
4. 15 releases (8.5 years from now) after GHC 8.6 `-XNoStarIsType` will be removed.
I would rather reword this to “may be removed”, and leave it to the future GHC developers to make the call. It may be that they decide that the cost keeping the StarIsType code around is not that big, and that the benefit of running old code with less effort is higher, and I see no reason to force their hand at this point. Instead of forcing, we should at most give a mandate. Cheers, Joachim -- Joachim Breitner mail@joachim-breitner.de http://www.joachim-breitner.de/
