I'm working on a series of SPM packages that work together, each of which has multiple targets within. I'm trying to figure out how much of my code to mark with @inlinable in order to allow the compiler to do cross-module optimizations.
Doing everything public and used across packages makes sense, do I also need to do the same thing for things used across targets within the same package? (I think the answer is yes for the same reason I need to mark those as public at least until the upcoming package access modifier is available).
