Thanks, I just did a simple test:

https://gist.github.com/run-dlang/88cefdde8bb7f61f173ad11b2a03d5ee

(BTW, https://run.dlang.org/ is not stable these few days).

```
import core.thread;
import std;
import std.parallelism;

shared string[string] aa;

void fun() {
   foreach (i; 0 .. 5) {
     writeln("fun", i, aa);
     foreach (num; parallel(iota(5))) {
         // writeln(num);
     }
     Thread.sleep(5.seconds);
   }
}


void main() {
     writeln("start", aa);
     auto aaTemp = [ "abc" : "123" ];
     aa = cast(shared)aaTemp;
     writeln(aa);
     foreach (num; parallel(iota(5))) {
       auto t = new Thread({fun();}).start();
     }
}
```

run result:
```
start[]
["abc":"123"]
fun0["abc":"123"]
fun0["abc":"123"]
fun0["abc":"123"]
fun0["abc":"123"]
fun0["abc":"123"]
fun1["abc":"123"]
fun1["abc":"123"]
fun1["abc":"123"]
fun1["abc":"123"]
fun1["abc":"123"]
fun2["abc":"123"]
fun2["abc":"123"]
fun2["abc":"123"]
fun2["abc":"123"]
fun2["abc":"123"]
fun3["abc":"123"]
fun3["abc":"123"]
fun3["abc":"123"]
fun3["abc":"123"]
fun3["abc":"123"]
fun4["abc":"123"]
fun4["abc":"123"]
fun4["abc":"123"]
fun4["abc":"123"]
fun4["abc":"123"]
```

looks like different threads can read the same `aa` contents. So 
at least it's working.
