quoting from there:
"The type of thisTid is Tid, but its value has no significance for the
program. Further, both threads report it to be surprisingly at the same
address:
Owner : Tid(std.concurrency.MessageBox), address: 809C360
Worker: Tid(std.concurrency.MessageBox), address: 809C360"


Likewise with writeln(&Thread.getThis);

How would I print a number/string that uniquely identifies a thread?

Tid is an opaque type, writeln(thisTid) isn't of any use.

struct Tid
{
private:
    this( MessageBox m )
    {
        mbox = m;
    }


    MessageBox  mbox;
}
