No, I don't agree. Why should I provide functions that are not meant to be 
called, ever?

Because, if you do, the class becomes unusable outside libkdecore. Since 
it's meant to be used, removing is out of the question.

Ok, so operator== will return false always and qHash will return 0? What's 
the use?

They are not comparable and they are not meant to be used in a set. I 
still fail to see why we should create functions that are not meant to  
be used by anyone, ever.

How about not generating QSet<KResolverEntry>? It's not supposed to, since 
the set isn't supposed to exist.
