Reduced it a little:

----
module z;

import std.stdio;
import std.concurrency;
import core.thread;

struct Variant {
     void function() fptr = &handler;
     static void handler() {}

     ~this() {
         fptr();
     }
}

void _get(Tid id) {
     id.send(Variant());
}

void supervisor() {
     receive(&_get);
}

void main() {
     Tid supervisorTid = spawn(&supervisor);
     supervisorTid.send(thisTid);
writeln("TUQLUE");
     receive(
         (Variant a) {}
     );
writeln("42");
     thread_joinAll();
}
