Um es ganz kurz zu sagen: Antiamerikanismus hat in Europa einen ganz anderen Stellenwert und zwar, wie diese Studien alle zeigen, ist es das einzige Vorurteil, das positiv mit Bildung und social standing korreliert.

In Deutschland wird es keine Revolution geben. Grund: es ist verboten.

Sinngemäßes gab es schon reichlich. So formuliert find ich es allerdings am treffendsten. Oder wie sonst erklärt man sich die Ruhe auf deutschen Straßen angesichts der Erschaffung einer neuen Aristokratie?

Those who cannot remember the past are condemned to repeat it.

As I posted here, virtual inheritence in C++ is a pain. Today I realized that it is also viral.

Suppose the same inheritence as the last time and add a new class D inheriting from B1. As in the former case there was a diamond the inheritence between A and B1 is virtual. From D's point of view you have the following code:

class A { 
public:
    A(int i) { /* ... */ }
};

class B1 : public virtual A { 
public:
    B1() : A(0) { }
};

class D : public B1 {
public:
    D() : B1() { }
};

This is a normal inheritence scenario. D's constructor calls its parent constructor and this one calls the grand parent's constructor and everything is fine, right? No. this example does not compile. GCC says: " In constructor 'D::D()': error: no matching function for call to 'A::A()'".

Yeah, right, D must call its grand parent's constructor, because B1's inheritence from A is virtual. This means: once you decide to use a class as the top of a diamond this has consequences for all uses of this class. Args!
