Nesting a Tid in a struct is interpreted as having local 
aliasing, though a bare Tid is not.

This doesn't work, though commenting out "receiveOnly!S()" and 
"tid.send(S(thisTid))" works:
-----
import std.stdio;
import std.concurrency;

void main() {
     auto thread = spawn(function void(Tid tid)
                         {
                             tid.send(thisTid);
                             tid.send(S(thisTid));
                         }, thisTid);
     receiveOnly!Tid();
     receiveOnly!S();
}

struct S {
     Tid tid;
}
