#5483: [with patch; needs work] Add explain_pickle module; allow overriding
class
lookup for unpickling
-------------------------+--------------------------------------------------
Reporter: cwitty | Owner: cwitty
Type: enhancement | Status: new
Priority: major | Milestone: sage-4.0.1
Component: misc | Keywords: pickling

Comment(by cwitty):
This appears to be a difference in Python's repr(), possibly between
Python 2.5.2 (from Sage 3.4.2 on my laptop, where I developed the patch)
and Python 2.5.4 (from Sage 4.0 on sage.math).
Python 2.5.2:
{{{
>>> v = ([],)
>>> v[0].append(v)
>>> repr(v)
'([([...],)],)'
}}}
Python 2.5.4:
{{{
>>> v = ([],)
>>> v[0].append(v)
>>> repr(v)
'([(...)],)'
}}}
I don't have time to experiment further right now, but I would suggest
changing the expected output to the new version, and if it's consistent
across all the test platforms then chalk it up to a change in Python and
call it good.
