Thanks for the thorough explanation. I understand now why this is complex and seems elm-review is bound by the same restrictions as the compiler I guess. Have made some progress so might continue on it but got a bit uninspired by the fact that elm-review doesn’t check dependencies. Did not know/realize that was the case which makes pursuing this not very worthwhile. I have learned something about writing elm-review rules at least. 😃
