Replying to [comment:1 mabshoff]:
> Ooops, but this does seem to expose some problems:
Sorry, I did not do any tests, since I thought that weak references Just
Work (c), and so the change from a dictionary to a WeakValueDictionary
would be almost trivial.
> And something this low level will definitely '''not''' go into 3.4.2 at
this stage.
Again sorry. Since I thought it is almost trivial, I concluded it could
easily be in the next distribution.
If weak references break cython code at a very fundamental level then I
see ''no chance'' for my approach to work, unless Cython changes.
Won't fix, then?
