> By "pickling" maybe you mean "caching"? I didn't make any changes at
all, whatsoever to caching. The only actual change my patch makes is that
the default __reduce__ method is now used when explicitly pickling residue
fields. Before pickling residue fields just resulted in a big error.
So what I do can't possibly fix any bug that wasn't very explicit before
(i.e., "pickling doesn't work at all").
OK, I just don't know what I am talking about....
