What's changed since it was last discussed? I don't think the objections were centered in the implementation, so I don't see what "whatever is remaining to get the change merged" would be. AFAICT at best it's a *very* small improvement[1] and fractures Haskell syntax even more around extensions -- tooling etc. will need to understand even *more* syntax extensions[2]. Regards, [1] If you grant that it is indeed an improvment, which I, personally, don't think it is. [2] I think most people agree that this is something that should perhaps be handled by something like https://github.com/haskell/haskell-ide-engine so that it would only need to be implemented once, but there's not even an alpha release yet, so that particular objection stands, AFAICT. _______________________________________________ ghc-devs mailing list [email protected] http://mail.haskell.org/cgi-bin/mailman/listinfo/ghc-devs
