Prefix/Postfix increment operators

by

It is more idiomatic to call the prefix increment of the object itself in the postfix increment:

X operator++(int)
{
    X copy(*this);
    ++*this;         // call the prefix increment
    return copy;
}

The logic of incrementing an X object is thus solely contained inside the prefix version.
