Boxing a cached struct

[derolf]

Is there a nicer way to create a reference to a cached struct inside another struct?

Current workaround:

@Equatable
@Immutable
struct Big {
...
}

class BigReference {
    @Cached
    property big: Big { get }
}

@Equatable
@Immutable
struct Thing {
  big: BigReference
}

Ideally, this would be nice:

@Equatable
@Immutable
struct Thing {
  @CachedReference
  big: Big
}

The semantics of @CachedReference big: Big would be:

• C++: shared_ptr<Big> big field in Thing
• Java/Swift/Dart: Access to big will always yield the same cached object.

Sounds like pretty rare case. Currently your approach looks like only possible.
