Thanks for your input. We are considering a more advanced model (David Roe has lots of ideas on this front), but this falls outside of the central focus coercion scheme. (This is one reason to use _repr_ rather than the Python __repr__ so that the base object's __repr__ can do more sophisticated things (although now it just calls _repr_). - Robert --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
