I would any day argue that it stems from bad design not to be able to both
allocate an object on the heap and on the stack. But I have not followed
the discussion about this and therefore I don't know what made you all
agree that it is all right to impose this restriction. Could someone
enlighten me? (I'm not trying to reopen a debate; I just really want to
know).

But if it is necessary, why not just declare the new or delete operator
private? This way you at least get a compile time error and a bunch of
"why the he..." messages on kde-devel.
