Write some C functions -callable from Python- which will be used to get
and set the variable value.
>From inside Python, declare a property with getter and setter which
will call your C functions.
This works fine for object attributes. If you want to trap references
to local or global "variables", I think you could provide customized
dictionaries for locals and globals, but I'm not sure if it works
really.
