I'd previously added an instance from `ForIn'` to `ForIn`, but this then caused some non-defeq duplication. It seems fine to just remove the concrete `ForIn` instances in cases where the `ForIn'` instance exists too. We can even remove a number of type-specific lemmas in favour of the general ones. |
