Change Manager: Verified that:

• Solution is implemented:

  • The code proposed compiles and passes all tests. Details:
    Build log: https://app.travis-ci.com/github/Copilot-Language/copilot/builds/272222180

  • The solution proposed addresses the necessary modification to cabal packages. The following docker image installs copilot enforcing the new version via compiler constraints. It prints the message "Success" at the end if all completes correctly, and shows an error message otherwise.
