Re: [Haskell-cafe] [ANNOUNCE] GHC 8.6.1-alpha1 available

I (really) should have known better: this change is intentional. GHC 8.6 changes the way that * is parsed in types. Specifically, * is always parsed as if it is a synonym for Type (that is, the kind of things like Int and Bool), not a binary operator. If you want it to be a binary operator, you must specify -XNoStarIsType. Richard

The parser seems to be broken. Attempting to build basement http://hackage.haskell.org/package/basement yields:

Basement/Nat.hs:15:46: error: parse error on input ‘*’ | 15 | , type (<=), type (<=?), type (+), type (*), type (^), type (-) | ^

I'm not 100% sure where to report bugs for the alpha.

The GHC development team is pleased to announce the first alpha release leading up to GHC 8.6.1. The usual release artifacts are available from

https://downloads.haskell.org/~ghc/8.6.1-alpha1 https://downloads.haskell.org/~ghc/8.6.1-alpha1

This is the first release (partially) generated using our new CI infrastructure. One known issue is that the haddock documentation is currently unavailable. This will be fixed in the next alpha release. Do let us know if you spot anything else amiss.

As always, do let us know if you encounter any trouble in the course of testing. Thanks for your help!

Cheers,

- Ben
