This proposal:
- Adds support for interfaces requiring other types than `Self` to implement interfaces, as in:
```
interface IntLike {
impl i32 as As(Self);
// ...
}
```
- Defines requirements on how to satisfy those requirements that have a `where` clause.
- Extends `observe` declarations to include saying a type implements an interface, so code can provide a proof instead of the compiler having to perform a recursive search.
