Comment (by SimonKing):
Hi Nils,
I guess we don't really need to take care of `print D`.
Now, I plan to create a follow-up ticket. Namely, I notice that in
different places in Sage we use something like a "weak value dictionary
without callbacks", for example `sage.modular.etaproducts._cache`: This is
a normal Python dict, but its values are weak references.
Hence, it would make sense to use a proper
`sage.misc.weak_dict.WeakValueDictionary` instead.
