+##   1. Crash ensues if you attempt to change the mask of a read-only
+##      MaskedComboBox after initial construction.
+##   2. Changed strategy of defining Get/Set property functions so that
+##      these are now generated dynamically at runtime, rather than as
+##      part of the class definition.  (This makes it possible to have
+##      more general base classes that have many more options for configuration
+##      without requiring that derivations support the same options.)
+##   3. Fixed IsModified for _Paste() and _OnErase().
+##
+##   Enhancements:
+##   1. Fixed "attribute function inheritance," since base control is more
+##      generic than subsequent derivations, not all property functions of a
+##      generic control should be exposed in those derivations.  New strategy
+##      uses base control classes (eg. BaseMaskedTextCtrl) that should be
+##      used to derive new class types, and mixed with their own mixins to
+##      only expose those attributes from the generic masked controls that
+##      make sense for the derivation.  (This makes Boa happier.)
+##   2. Renamed (with b-c) MILTIME autoformats to 24HRTIME, so as to be less
