In structure design ... and especially when you design a hardware that is meant to be automatically converted into verilog or even logic gates, I personally would really want to have a one-to-one relationship of the python-objects vs the actual hardware structures. The granularity is at signal/bit level. This is why I really think giving a special assignment in python which users could override is really helpful, rather than having to have this kind of special case: if you do "self.abc = thing" descriptor mechanism is invoked, but the very next line if you do "abc = thing" ... nothing will happen. This special case can be completely removed and having a much better conceptual consistency if the "<==" assignment operator always behaves the same, doesn't matter if it is "self.abc <== thing" or "abc <== thing". _______________________________________________ Python-ideas mailing list Python-ideas@python.org https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
