+   Modern undo/redo system does not systematically invalidate all pointers anymore.
+   Some data (in fact, most data, in typical cases), which were detected as unchanged for a

 Undo & Library Data

+Abusing RNA property callbacks
+------------------------------
+
+Python-defined RNA properties can have custom callbacks. Trying to perform complex operations
+from there, like calling an operator, may work, but is not officialy recommended nor supported.
+
+Main reason is that those callback should be very fast, but additionally, it may for example
+create issues with undo/redo system (most operators store an history step, and editing an RNA
+property does so as well), trigger infinite update loops, and so on.
