[Python-Dev] weakattr (original) (raw)

I like the added functionality offered with weakattrs as defined. I'm not terribly in love with the syntax of their creation, and I'm curious as to how it plays with slots weakattrs are data descriptors, just like properties etc. they are part of the class, not the instance, so there shouldn't be any trouble with mixing those with slots

moreover, adding those to stdlib is very staight-forward. we don't even need to introduce a new module. if people show interest, i'll write a bit of a longer doc string and add some unit tests (although there's not much to test :) )

Toss it out in python-list, I think some people over there would be able to offer more feedback. will do... although i doubt they will offer any

I like the added functionality offered with weakattrs as defined. I'm not terribly in love with the syntax of their creation, and I'm curious as to how it plays with slots (not quite having the time to look at its implementation right now), but it is quite explicit, so I can get past that. It would allow us to say, "stop using del, use weakattrs", but I'm not sure how well that would work, generally.
