Thanks.
I don't know if it's *correct* or not, but I think I did this
at the time to work around it.
```
shared string[string] aa;
void main()
{
auto aaTemp = [ "abc" : "123" ];
aa = cast(shared)aaTemp;
}
```
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.
