Thanks for clarifying - I knew I said something very wrong. But (I'm just
asking this and not arguing, because it's been ages since I did any
"real" C++): when you pass an int as a variable to a function,
you are actually passing a variable by value, thus creating a new variable
in the function that was called, and then you can change the value in that
function without affecting the original one, right (nevermind passing
actual pointers for now)? But when you pass that "d" to a
function, you're passing a "pointer" (reference? handle? what do
you call it now?) to that object and *not* creating another object in the
scope of the function that was called, right? Is it even possible to
actually pass an object by value to a function? This is basically what I
meant by "d" being more of a pointer than a variable, it's just
hidden by the compiler / language.

Or did I just confuse poor ol' schoolboy Geo more?
