So either don’t expect swift secretarial responses, or act secretarial in my absence. Cheers, Joachim -- Joachim Breitner mail(a)joachim-breitner.de http://www.joachim-breitner.de/

#604: do not let -XScopedTypeVariables imply -XTypeAbstractions, rec: accept
by Joachim Breitner 02 Aug '23

02 Aug '23

Dear committee, John Ericsson in https://github.com/ghc-proposals/ghc-proposals/pull/604 proposes an amendment to #448. I’ll shepherd this myself. Status Quo: ScopedTypeVariables implies TypeAbstractions. New behavior: TypeAbstractions needs to be enabled explicitly. (Plus, as a compat feature, ScopedTypeVariables&TypeApplications enable TypeAbstractions, with a deprecation warning upon use.) John makes a good argument that it’s odd to expand the meaning of an existing extension like ScopedTypeVariables without need, and the proposed way sounds good to me, so I recommend to accept this. This is a minor change and would be good to have clarity soon. If no discussion happens, I’ll merge in a week. I am particularly keen on feedback from Richard (original author) and Arnaud (original shepherd), of course. Cheers, Joachim -- Joachim Breitner mail(a)joachim-breitner.de http://www.joachim-breitner.de/
