Well maybe you all knew that, yet while I read the thread, I saw
noone mentioning this possibility to get what the OP seemed to
want. I also did't see other posibilities. Your idea as an alternative
only came as a reaction to my idea.
I know my idea as presented was cumbersome. Maybe it can be worked out
more, maybe with the help of decorators to be less cumbersome.
I also know it can be circumvented in CPython.
Yet I think is was usefull to explore what is already possible in Python
instead of just argueing about whether people need it or not
I always find it odd when the "you don't need it" argument is used.
Of course that is correct, put python has acquired a lot of things
that were originnally labeled "you don't need it". So why people
still use it against introducing something, is something I don't
