Comment (by saraedum):
I had a look into this. Except for one place (which could certainly be
worked around somehow), the doctests seem to fail because caching doesn't
work anymore. Would there be something wrong with adding a
{{{_cache_key()}}} to {{{SageObject}}} which per default returns
{{{self}}}. Only if the element is not hashable (but should be) it could
return something that is actually a unique key for this element —
something like {{{self.dumps()}}} maybe.
I gave it a try (see attached patch). The only doctests that fail seem to
be a few places where {{{self.dumps()}}} doesn't work and a one problem in
{{{sage/modular/overconvergent/weightspace.py}}}.
