Thanks. One can see this documented in
http://dlang.org/operatoroverloading.html#equals
But
1: how can one override this behavior
2: what is the design reason for this
Especially: how can one implement side effects

There is now way in D other than
class C{
override bool opEquals( Object o){
return true;
}
}
unittest{
auto c= new C;
assert( c == c);
}
`rdmd --main -unittest -cov' shows, that opEquals is not
executed. Why?
