I would like to use kind equality, which seems only present in GHC head for now.
I made a system-install of GHC, and in my project I added a
resolver: nightly-2016-12-31 compiler: ghc-8.1.20170103
resolver: name: snapshot location: snapshot.yaml
I can see using
stack path that it picks the correct compiler.
When I build my project I now have
In the dependencies for array-0.5.1.1: base-18.104.22.168 must match >=4.5 && <4.10 (latest applicable is 22.214.171.124) needed due to bookkeeper-0.2.4 -> array-0.5.1.1
How can I override from my project the upper-bound declared by array-0.5.1.1, which is probably not actually required ?
