In D nothrow functions can throw errors.

Of course, ignore me :-)


You could do something like this:

void foo() @nogc
{
   static err = new Error();
   if (badthing)
   {
       err.setError("badthing happened");
       throw err;
   }
}

To be mutable err also needs to be __gshared.

But then it isn't thread safe. Two threads trying to set and 
throw the same Error is a recipe for disaster.
