By the time the constructor runs, an instance has already been
created.  But if you throw an exception in the ctor, it's impossible
for a reference to that instance to be stored anywhere, unless you
store it within the ctor itself, i.e.

this()
{
    someGlobal = this;
    throw new Exception("foo!");
}
