Re: [ghc-steering-committee] #364: Unify Nat and Natural, recommendation: accept

I am fine with this change too. Joachim, I'd be curious to see an example of the hurdle you run into, if there is a simple example illustrating it. On Thu, Oct 1, 2020 at 4:22 AM Spiwack, Arnaud wrote:

I fail to find a downside as well. I would still like to insist on the motivation section to feature an illustrative example before we merge the proposal, though. But the rest is good with me.

Aye. Tidies this up, and I see no downside.

Dear all,

I recommend that we accept this proposal. The only problematic (read, not backwards-compatible) bit is the case of a type class having instances for both `Nat` and `Natural`, but that seems very unlikely.

Something which I thought about was whether any of `Nat` or `Natural` were implementing something akin to Peano naturals (so we could have inductive instances working on Zero and (Succ n)), both none of both do, so the alignment seems correct to me.

Regards,

Alejandro
