It may also be useful to allow the indirect modifier directly on struct and enum to allow type authors to indicate that all instances should be indirect.  Do you think it would it be worthwhile to pursue this proposal now?

Sure.  I’m still curious about ideas you have for the future.

I’m also interested in your feedback on whether a proposal around indirect is something worth pursuing right now or whether that is something that should wait until after Swift 3.
