-// One of the most important features of the new Io system is
-// structured cancellation!
-//
-// Every Future has a .cancel() method that:
-//   1. Requests the task to stop (via error.Canceled at the
-//      next "cancellation point")
-//   2. Waits for the task to actually finish
-//   3. Returns whatever result the task produced
-//
-// A "cancellation point" is any Io function that can return
-// error.Canceled - most commonly io.sleep():
-//
-//     fn myTask(io: std.Io) u32 {
-//         io.sleep(...) catch |err| switch (err) {
-//             error.Canceled => return 0,  // handle gracefully
-//         };
-//         return 42;
-//     }
-//
-// This is fundamentally different from killing a thread -
-// the task gets a chance to clean up and return a value!
-//
-// Fix this program: the slow task would take 10 seconds,
-// but we cancel it after 1 second. The task should detect
-// the cancellation and return early.
-//
