Well, it ought to go to infinity, wrap to negative infinity, and then back up to zero, of course :). Just treat it like the one-point compactification of the real line, going the long way around. Should the following be valid? [10,20..15] for the list [10,20,19,18,17,16,15]. Perhaps there should be a distinction between [10,11,..,0] and [10,11..0]. [10,11,..,0] is an error, while [10,11..0] is okay (i.e., without the commas, the step is assumed to be 1 or -1). -Jason --~--~---------~--~----~------------~-------~--~----~ 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://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
