Binding properties pattern

Binding properties with transformations can be achieved through reducing the transformation function to the problem of binding properties, and the function can be imaginary consider as Type Conversions.
124:
Infinite loops can be eliminated by blocking the signal, or comparing the assigned value with the property value before assignment, or eliminating unnecessary assignments.
99:
As an alternative to the aspect-oriented implementation of mutual properties, property binding can be proposed. In LibPropC++ C++ library it is implemented too.
121:
There are two types of binding. One-way binding should be applied when one of the properties is read-only. In other cases, two-way binding must be applied.
106:
Its use is not transparent as it requires to be declared necessary object attributes as properties and appropriate accessor methods must be provided
174:
Properties are being kept synchronized automatically. Between library calls they always have the values expressed by the EqualityConstraints.

Accomplishing the binding (i.e. connecting the property change notification in an event handler) may be like as follows:

Binding of attributes in LibPropC++ is not designed to replace method calls

Code sketch for one-way binding may look like as follows:

Some weakness in the LibPropC++ (with property binding):

The library does not maintain an interaction history.
