dontCheck for haskell packages doesn't remove dependencies

[MangoIV]

Describe the bug

using dontCheck doesn't remove the need for dependencies

Steps To Reproduce

Steps to reproduce the behavior:

nix build github:jfaure/irie-lang/4aac3edc221e8309396c8a547adfab20f3e961f7

Expected behavior

dontCheck removes the need for depending on fused-effects as it is only a dependency for the testsuite https://github.com/jfaure/Irie-lang/blob/4aac3edc221e8309396c8a547adfab20f3e961f7/flake.nix#L27

Additional context

• callHackage is used

[maralorn]

This is more or less an implementation detail of how we use callPackage. The function expects a fused-effects argument, and if that is not in scope it fails. I would appreciate a fix for that but I don‘t know of one (at least not without butchering debugging).

Nevertheless fused-effects is only expected as a function argument. It will never be used in the function if you use dontCheck and fused-effects is only used in the test. That means you can fix your build by passing fused-effects = null.

Thank you. This is pretty much what I expected.
