(I assume that nothrow isn't meant to be there?)

What if the exception needs information about the error?

You could do something like this:

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

However, that raises a second question: since err is allocated 
when a new thread is created, does that mean @nogc functions 
cannot create threads in the presence of such static 
initialisation?
