    Implementing a move assignment operator using an established
    technique (move-and-swap, pure swap) is just boilerplate.
    Here's a couple of *private* macros for convenience.

    To know which one to use:

    * if you don't have a move constructor (*) => use pure swap;
    * if you have a move constructor, then
      * if your class holds just memory (no file handles, no user-defined
        datatypes, etc.) => use pure swap;
      * use move and swap.

    The preference should always go for the move-and-swap one, as it
    will deterministically destroy the data previously held in *this,
    and not "dump" it in the moved-from object (which may then be alive
    for longer).

    The requirement for either macro is the presence of a member swap(),
    which any value class that defines its own special member functions
    should have anyhow.

    (*) Many value classes in Qt do not have move constructors; mostly,
    the implicitly shared classes using QSharedDataPointer and friends.
    The reason is mostly historical: those classes require either an
    out-of-line move constructor, which we could not provide before we
    made C++11 mandatory (and that we don't like anyhow), or
    an out-of-line dtor for the Q(E)DSP<Private> member (cf. QPixmap).

    If you can however add a move constructor to a class lacking it,
    consider doing so, then reevaluate which macro to choose.
