This code should be allowed:
--------------
import core.atomic, core.thread;
import std.concurrency;
import core.sync.barrier;

class Foo
{
    shared int a = 0;
    void bar(shared Barrier barrier) shared
    {
        while (1)
        {
            Thread.sleep(dur!"msecs"(10));
            if (a.atomicLoad() > 100)
                break;
        }
        (cast()barrier).wait();
    }
    void countup() shared
    {
        foreach (i; 0..200)
        {
            Thread.sleep(dur!"msecs"(10));
            a.atomicStore(i);
        }
    }
}

void main()
{
    auto barrier = new Barrier(2);
    auto foo = new Foo;
    spawn(&foo.bar, cast(shared)barrier);
    foo.countup();
    barrier.wait();
}

--------------
The Foo.bar is thread-safe. So, making new Tid by spawn with the shared member
function is no problem.
