typeid() woes

[Andrej Mitrovic]

test.d:

class Contact
{
}

class Friend : Contact
{    
    void reminder()
    {
        writeln("friend.reminder");
    }
}

unittest
{
    Contact c = new Friend; // c has type Contact but really refers to a Friend
    
    writeln(typeid(c));
    c.reminder();
}

This will not compile, as expected, since a Contact type doesn't have the reminder method.

But if I comment out the c.reminder() line, writeln will return "test.Friend". Why is that?
