#4698: [with patch, needs review] a single make_element function for pickling is
hard to maintain
---------------------+------------------------------------------------------
Reporter: burcin | Owner: burcin
Type: defect | Status: new
Priority: major | Milestone: sage-3.2.2
Component: algebra | Keywords:
---------------------+------------------------------------------------------
All subclasses of `sage.structure.element.Element` end up using
`sage.structure.element.make_element` for unpickling. This design is very
hard to maintain, especially when trying to keep backward compatibility
with older pickles.
Python's pickling protocol via `__getstate__()` and `__setstate__()` moves
the implementation of pickling/unpickling to the subclasses. [1] Attached
patch changes sage.structure.element.Element to use this protocol.
