Oh, I see.
So mtl
as in master is not buildable with installed version of transformers
, And IIRC that's intentiona? So we could have UNCONSTRAINED...
pushed new commit, let's see.
Good point, I didn't even notice the lower version bounds on transformers
... that would definitely explain that.
Maybe this isn't the best place to try out your new haskell-ci
feature, then. unix
and stm
experienced similar issues, so perhaps those would be better testing grounds.
I believe I tried this in https://github.com/haskell/mtl/commit/1c110d117d4e5a554d96a39879c14791696c634d, but it still failed to build on GHC 7.8: https://travis-ci.org/haskell/mtl/builds/399714580
