That’s really a problem with the dependency.
Exactly my point. I didn’t change anything except GHC; but now my dependency fails to compile. Most of my work (when doing an upgrade) goes into fixing dependencies, not my own code.
Regarding warnings, if my example is bad, that’s on the example; but the problem (I have) still remains.
In general, I feel that with this proposal, if I have code + libraries that compiled under Stable2024, they willcontinue to compile under that “pack” for at least 6 years; 3 of those years will be when a new “Stable” is available, giving me lots of time to migrate to a new “pack” and newer GHCs.
