Re: Request for feedback: deriving strategies syntax

Just a quick thought: The term "built-in" seems a bit myopic IMO since all these extensions are in a sense built-in, and especially if any of them make it into Haskell 2020. I wonder if "standard" would be better or something similar. On Jul 17, 2016 08:57, "Ryan Scott" wrote:

I think it would be a great idea. That being said, given that it's not be approved yet, I'm in no position to require it. Ryan, I'll leave this call up to you. If you would like to write up a proposal using the template in the repository then by all means let's give it a try. If not, then no worries; we can continue here.

I hadn't thought of using ghc-proposals for this, and since it's still in a nascent state, I'll opt to continue using the GHC devs mailing list for this dicussion.

Alexey,

I can't see how this doesn't require changes to Template Haskell.

You are correct, I got my wires crossed when trying to recall the details. I think what I (sloppily) remembered was that in an earlier revision of https://phabricator.haskell.org/D2280, I had implemented a pragma-based approach that didn't require a language extension. But I now consider that a mistake, so I've introduced the -XDerivingStrategies extension, which should be required regardless of what syntax we decide to adopt.

Should we test drive https://github.com/ghc-proposals/ghc-proposals https://github.com/ghc-proposals/ghc-proposals on this proposal?
