…member references until future Swift version Static member referenced were marked as `@Sendable` by `InferSendableFromCaptures` because metatypes used to be always Sendable which is no longer the case, so in order to maintain the source compatibility we need to downgrade missing `@Sendable` to a warning for unapplied static member references. This affects primarily operators at the moment because other static members form a curry thunk with a call inside and would be diagnosed as a capture. Resolves: rdar://150777469 (cherry picked from commit a57310b)
