So if we can have a single package with the sensible infrastructure and within that package have two ASTs, one for "simple" Haskell and one for "extended" Haskell then that seems like an ideal combination to me.
The only problem is that it will take some work to adapt haskell-src-exts to Haskell 20nn. I spoke to Niklas about this. He has in principle volunteered to take on the task, but he can't start on it for a few months. And I don't think it would be wise to make the package name changes and end-of-life the current haskell-src until this is done.
Yes, I agree with both Duncan and Yitz here. It would be some monkey work to introduce a "simple" AST, but nothing tricky in principle. I wouldn't mind adding such an AST to haskell-src-exts, and I think that's the best solution long-term. But as I'm on the final stretch of my PhD thesis work, I simply don't need more opportunities for procrastination right now, hence the "few months"... ;-)
So unless someone else can do the work, we may have to wait until the following HP release.
I believe that would be the case regardless, no actual proposal for adding haskell-src-exts has been written yet. Cheers, /Niklas
