But you haven't shown a C++ solution either, since the cast in your example doesn't work.

If a constructor is added like in the following example, it will work. Think that was the intention of Tony.

class Document
{
public:
Document(){}
static Document Load() { return Document(); }
};

class MyDocument : public Document
{
public:
MyDocument() {}
MyDocument(Document& s) : Document(s) {}
static MyDocument Load() { return Document::Load(); }
};

int main(int argc, char* argv[])
{
MyDocument s = MyDocument::Load();
return 0;
}
