Sorry for coming into your discussion. I actually appreciate that x/y
and print x/y do different things, for the following reason.
If someone defines some sage object X and just types
sage: X
then the command is very short, and when i ask a short question, the
answer ought to be short as well.
On the other hand, if the user's demand on displaying X is more
elaborate, such as
sage: print X
then the displayed information should be more elaborate as well.
Hence, it makes sense to me that X.__repr__() (which is invoked by
sage: X) just returns a brief description, while X.__str__() (invoked
by sage: print X) can be more lengthy and should be descriptive enough
to reconstruct X.
Yours
Simon
