Re: Getting comonad into base

Ollie: It's for giving my own instances. I suspect most of the reasons that comonads feel uninteresting is that they've been relegated to a second-class citizen in the ecosystem. chessai: I'm not proposing the whole package; just the class. I can't imagine the migration path is any harder than putting an ifdef into the comonads package. On Fri, Sep 11, 2020 at 12:06 PM chessai wrote:

Hi Sandy,

I think this would be a good candidate for the new Libraries Proposal process, modelled after ghc-proposals. See https://github.com/haskell-core/core-libraries-proposals

I recommend writing a proposal there. In particular, for changes like this, one of the things that needs the most thought is the story around a migration path.

Hope this helps.

Thanks

Hi all,

I frequently regret the lack of having the Comonad class in base. Are there any good reasons for its absence? If not, I can get started on a patch.

Best, Sandy _______________________________________________ Libraries mailing list Libraries@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/libraries
