I'm not sure I understand, could you elaborate? "correct" as in "the merge error is right" or "should work as written". Also there are a number of `export struct` in the tests, but you are saying this should not be included in the modules? How would this work? > Even if you put them into the global module fragment, I think we should try > to look other places like `isSameEntity` to solve this. Sure, but this first requires the hash to be identical, no? My understanding is that two (structurally) identical Decls must always hash to the same value, but the same value does not imply that `isSameEntity` and friends eventually agree (due to hash collisions).
