+# ## TRICKY BIT: to avoid a ton of boiler-plate, and to

+# ## control parameter so we never forget to add the
+# ## functions when adding parameters, this loop
+# ## programmatically adds them to the class:
+# ## (This makes it easier for Designers like Boa to
+# ## deal with masked controls.)
+#
+# ## To further complicate matters, this is done with an
+# ## extra level of inheritance, so that "general" classes like
+# ## MaskedTextCtrl can have all possible attributes,
+# ## while derived classes, like TimeCtrl and MaskedNumCtrl
+# ## can prevent exposure of those optional attributes of their base
+# ## class that do not make sense for their derivation. Therefore,
+# ## we define
+# ## BaseMaskedTextCtrl(TextCtrl, MaskedEditMixin)
+# ## and
+# ## MaskedTextCtrl(BaseMaskedTextCtrl, MaskedEditAccessorsMixin).
+# ##
+# ## This allows us to then derive:
+# ## MaskedNumCtrl( BaseMaskedTextCtrl )
+# ##
+# ## and not have to expose all the same accessor functions for the
+# ## derived control when they don't all make sense for it.
