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;
}
