[Python-Dev] weakref enhancements (original) (raw)

I'm sceptical that these would find use in practice. [..] Also, I question the utility of maintaining a weakref to a method or attribute instead of holding one for the object or class. As long as the enclosing object or class lives, so too will their methods and attributes. So what is the point of a tighter weakref granualarity?

i didn't just came up with them "out of boredom", i have had specific use cases for these, mainly in rpyc3000... but since the rpyc300 code base is still far from completion, i don't want to give examples at this early stage.

however, these two are theoretically useful, so i refactored them out of my code into recipes.
