Doesn't work:
```
import std.datetime.systime;
struct Unshared(T)
{
private T value;
T get() shared { return cast(T)value; }
alias get this;
void opAssign(T v) shared { value=cast(shared)v; }
}
shared synchronized class A {
private Unshared!SysTime t;
this() {
t = Clock.currTime;
}
}
void main() {
shared A a = new shared A;
}
```
Gives you:
onlineapp.d(6): Error: non-shared const method
std.datetime.systime.SysTime.opCast!(SysTime).opCast is not callable
using a shared mutable object
onlineapp.d(6): Consider adding shared to

onlineapp.d(8): Error: template std.datetime.systime.SysTime.opAssign
