I agree with this objection. I'm thinking of a case like QQ['x','y','n'] where n is some sort of parameter which you might commonly offset with a semi-colon on paper. To let n somehow get put ahead of x and y is not good at all. Now, my example might be a bad one since it would be strange to have this other parameter be just another variable in your polynomial. In any case, I think that (artificial) parameter orders when given in a list must be respected. I think it's only consistent with the way we always do function notation on paper. -- Joel --~--~---------~--~----~------------~-------~--~----~ 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/ -~----------~----~----~----~------~----~------~--~---
