Yes. We're making good progress on the new coercion model (David Roe and I were working on it last night, he finished Rings), but it is not 3.0 material (both for timing and stability reasons). To find out what the "new coercion model" is see http:// wiki.sagemath.org/days7/coercion . It is orthogonal to most development but I think you in particular keep hearing a lot about it because it was created to address exactly the kinds of concerns and annoyances with Sage that you so often bring up :). Also, if someone proposes doing something that is a complete reduplication of work that either has been done (or is rendered unnecessary) by the coercion fixes I try and point that out. - 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 -~----------~----~----~----~------~----~------~--~---
