executeInNewThread caller should have an access to created thread. For example to set daemon thread:

import std.parallelism;
import core.thread;

void long_operation() { Thread.sleep(dur!("seconds")(5)); }

void main()
{
    Thread task_thread = task!long_operation.executeInNewThread;
    task_thread.isDaemon = true;
}
