Sorry to resurrect an old thread, but then how can one update a SysTime
field in a shared class? Like this (using a synchronized class for
simplicity, this part works and the mutex acts as expected):
```
import std.concurrency;
import std.datetime.systime;
import core.thread;
public synchronized shared class A {
public:
void doSomething() {
// Doing something takes a couple of seconds.
Thread.sleep(2.dur!"seconds");
// How can we update the timestamp? Neither of those work
timestamp = Clock.currTime;
timestamp = cast(shared) Clock.currTime;
}
private:
SysTime timestamp;
}
void main() {
shared A a = new shared A;
spawn( (shared A a) { a.doSomething;}, a );
Thread.sleep(1.dur!"seconds");
spawn( (shared A a) { a.doSomething;}, a );
}
```
Of course the kludge (and what I'll be doing) is just to use __gshared,
but I expected this to be a convenience / hack to save you castings,
rather than the only way to achieve it.
