Hi,
I want to spawn several similar tasks and then wait for all of
them to complete to go on do some other things, like:
```d
void task(int id)
{
// do the stuff
}
void main()
{
foreach (i; 0..10) {
spawn(&task, i);
}
wait(?); // wait for all task to complete
doSomeOtherThings();
}
```
But I don't see a `wait` method for Tid, similar to Pid in
std.process.
What is the idiomatic way to do these things?
My current workaround is using messages:
```d
#!/usr/bin/rdmd
import std.stdio;
import std.concurrency;
void child(int id)
{
writeln("Starting child: ", id);
ownerTid.send(id);
}
void main()
{
foreach (i; 0..10)
{
spawn(&child, i);
}
for (int n = 0; n < 10; ++n) {
receive((int i) {
writeln("Received:", i);
});
}
}
```
But it is verbose and seems error prone.
