What is the standard pickle jar for and how do I update it
I started Trac #9907, which basically consists of a relocation of some general decorators into
sage.misc.decorators. However, after applying the patch, the doctest for
sage.structure.sage_object.unpickle_all fails. It seems to be because there is a standard pickle jar which still contains the information that the decorators are located in
Is it correct that there is such a pickle jar? In that case, what for, and how do I get about updating it and fixing my patch?
