Thank you I will try this.
What I found out up to now is to create a class inherited from an
fitting type
and overwrite the __setitem__ and __getitem__ method but haven't test
this
yet, something like that:

class test(int):
 __setitem(self, value)__:  C-Set-Func(value)
 __getitem(self)__: return C-Get-Func()

x=test()
x=     -> C-Set-Func called
y=x     -> C-Get-Func called

something seems not yet correct
