src/lib/Data/Variant/Excepts.hs:13:14: error:
    Unsupported extension: BlockArguments

Should be fixed by #3. Strangely the CI job fails, only for 8.4.4 while building mwc-random and I can't reproduce this locally for now.

Ah it's using a too recent version of random where thawGen is in another class.

Fixed upstream in haskell/mwc-random#89 but not yet released

[hsyl20]

Fixed and released: https://hackage.haskell.org/package/variant-1.0.1

[phadej]

Please make revision to https://hackage.haskell.org/package/variant-1.0 with correct bounds / other-extensions

Done: https://hackage.haskell.org/package/variant-1.0
