Hi!
Due to #9944, #9138 and #5, it will hopefully soon be possible to
move many methods from sage.rings.ring.Ring to
sage.categories.rings.Rings.ParentMethods, including cached methods.
The benefit of moving the code is that a MatrixSpace, which sometimes
is a ring and sometimes isn't, could

Interesting. Why can't this be done in memory? Are the files involved huge
enough that they won't necessarily fit in memory? And if so, shouldn't this
be more widely known, so that people don't fill up their disks? :)

When debuggin code that is loaded into or attached to a Sage session,

Sorry about that - I must have misplaced my brain this morning.
Yes - I guess I was implicitly thinking about (delta temperature).
