Description
Currently, both alloc::rc::Weak and alloc::arc::Weak are unstable. The somewhat vague reason for this is that weak pointers may not belong in this module. Now this has been addressed multiple times in #24028 and I have been observing this situation for a few months. However, as far as I can tell, nothing has happened so far.
Stabilizing my FRP library Carboxyl is currently blocked on this issue (see milibopp/carboxyl#47). Hence, I would really, really love to see this stabilized.
So my main question there is: is it really, as the instability note indicates, just a matter of discussing whether it should be moved to another module? Or is there anything more to it? In either case I would be happy to help out with anything that needs doing.
I did some archeology on the git logs. And, apparently @brson marked alloc::rc::Weak as unstable a year ago in cf8bfde. Shortly thereafter, @alexcrichton adapted this policy to alloc::arc::Weak in e5da6a7. So perhaps one of you could comment on the motivation behind that and whether it still applies today?
