I think something like this could be moved into library code, but for now I've kept it in this case study.

Making didSet sendable since it will typically be used in concurrent situations.

this is a fix that is independent of this PR. I also added a failing test that this fixes.

The downside of this PR is that it's a breaking API change pretty late in the game: ```diff -$0.defaultFileStorage = InMemoryFileStorage() +$0.defaultFileStorage = .inMemory ``` We could add public deprecated functions that emulate the old initializers if we think it's worth it... * wip * wip * wip * wip * wip * wip * fix for 5.7.1 * sync ups clean up * more docs * more tests * shared testing tiups * wip * wip * Fix typo.

This introduces a read-only version of
@Shared. It works much like@Shared, except you are not allowed to write to it. This can be useful for allowing features to hold onto shared state that it shouldn't be allowed to write to, as well as using it with external systems for which it does not make sense to "save" data to the system (e.g. remote config, feature flags, notifications, etc.).
