Actually yes! I started prototyping how the library-report modules could
like like in H2020 as an actual working prototype (needs at least GHC
8.6, as only GHC 8.6 has the MonadFail desugaring properly setup to make
this work seamlessly w/o the need for consumers to enable {-# LANGUAGE
RebindableSyntax #-}):
http://hackage.haskell.org/package/haskell2020
as this is the easiest way to empirically evaluate whether the
big picture makes any sense;
This is a real package with proper versioning that can be depended upon
by other packages on Hackage; breaking changes will be signalled via
major version bumps). This package can be used just like the old
`haskell2010` was used, i.e. in your `.cabal` file you simply state
build-depends: haskell2020 == 0.1.*
and do *not* declare a dependency on the `base` package.
Unfortunately I got distracted and haven't yet finished the delta to the
library report for AMP+MRP. I hope to get back to it soon to tie this
up.
Best,
Herbert
