+1 from me for keeping the two separate as well. While GHC may be the obviously prevalent Haskell compiler it is a far from the only one,

And I’d hate to have to look at a proposal for adding an extension to GHC (which would be riddled with GHC specific implementation specifics)

Rather than a clean specification.

 

Maybe I’m naïve but I also see the Haskell committees as doing more than just copy pasting what’s worked. But also evaluate how it can be done

Better. I can perfectly well see situations where the implementation in GHC ended up being less useful than It should be just because of

Implementation quirks/difficulties in GHC.

 

Cheers,

Sadly, I agree with this statement. And I think this is what we're trying to change.

My hope is that Haskell2020 will allow us to differentiate between standardized extensions and implementation-defined ones. A key part of this hope is that we'll get enough extensions in the first set to allow a sizeable portion of our ecosystem to used only standardized extensions.

But writing a new standard that encompasses prevalent usage will help to change the situation. And that's the process I'm hoping to contribute to.
