Just to confirm, this is only the first time, right? I am pretty sure this is because the coercion model tries to compute the construction tower and "pushout" one-variable at a time. This is to support stuff like sage: ZZ['x,y,z'].gen(1) + QQ['y'].gen(0) 2*y Of course it is bad when you have multi-variate polynomials in 100's of variables... Any ideas on how to handle both cases cleanly? - 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://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
