Re: [ghc-steering-committee] Please review #678: Amendment to ImportShadowing

I would like to hear back from the proposal author. If he's willing to incorporate Simon's spec, I would be very happy. I still accept the proposal as-is in the interest of making progress. Am Mo., 21. Okt. 2024 um 11:40 Uhr schrieb Matthías Páll Gissurarson < mpg@mpg.is>:

I’m in favor of the backward compatible one, it’s a bit more complicated but (I think) clearer. I’ve left some comments on the PR itself.

we'd be well served by a better spec for what `module M` means in an export list,

Well, that's the entire purpose of this amendment!

- Do you think it now gives a clear spec? - Do you prefer the alternative (more complicated, but backward compatible) spec I suggested here https://github.com/ghc-proposals/ghc-proposals/pull/678#issuecomment-2421884... ?

I'm in support. I agree with Simon's comment, we'd be well served by a better spec for what `module M` means in an export list, but this amendment is closer to what we would want.

I find it a little annoying that this isn't backward compatible. But on the other hand, it's a very obscure bit of Haskell semantics which is modified, module re-export is something that most people frequently get wrong anyway. At any rate, my feeling is that the proposed change is the right behaviour: if a module defines a function `foo`, and exports a *different* function `foo`, this is at least a smell, isn't it?

So, in favour.

Seems like a reasonable amendment, I'm in support.
