@isolated(any) There are cases where just a little more visibility and control over how to schedule asynchronous work can make all the difference.

Matt Massicotte explains Swift’s @ isolated(any): it records a function’s actor isolation and exposes it via an isolation property.

He shows how Task/TaskGroup use it for smarter scheduling and MainActor ordering, and says most callers can ignore it.
