+    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.
