Problem is python do not allow you to define new operators in the language itself, except those pre-defined you can modify their behavior. Even in case, if python would have been able to allow me to redefine the behavior of "=", e.g. by checking if the left hand side has a method (e.g. __assign__) to override the default behavior of the equal sign, I would be 100% happy already :) I have looked into all the existing operators that python supports which looks like an "assignment", none has been fallen in love with me. The example in Chisel w/ Scala is: they defined quite a few operators: ":=" for signal assignment, "<>" for bulk signal connections etc. And you can keep inventing new operators with which your design can look really elegant.
A note of caution: your design can look really elegant *as long as you know what your new operators mean*. If you don't, it's looks like incomprehensible noise. I have had far too many bad experiences with "clever" C++ with redefined operators to assume that "elegant" and "obvious" go hand in hand.
If you really must prat around with redefining assignment, make the relevant attribute a property.
