It seems to me like this should be factored into two pieces. The first part, the actual conversion, should really be a (canonical?) coercion from R[x, y, z] -> (R[x, y])[z]. The polynomial(var) function should be a helper that creates the correct rings and coerces. Does that seem reasonable? This is all contingent on such coercions existing :) Nick --~--~---------~--~----~------------~-------~--~----~ 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/ -~----------~----~----~----~------~----~------~--~---
