There is no other patch for using this preprocessor option. Any related improvements down the road will be about general improvements for error recovery, for example things like this:

- Introduce an `UnresolvedTypename` type instead of changing unresolved types to `int`.
- For `@interace A : B`, don't completely drop `B` from the super-class list of `A` if it is unresolved.

These kind of improvements are not conditional.
