Comment (by aschilling):
Hello Franco and Christian,
I folded the patches and added the links to the rank_function method from
is_graded and is_ranked. However, perhaps this was premature since like
Franco I get the pickling failure in the doctests which I also cannot
reproduce inside sage.
Any idea on how to fix this? I gues this introduced through Christian's
review patch by adding the height???
Best,
Anne
