Correct, that was the rationale. I disagree, if there is only one variable in the expression. > IIRC, previous conversations about this centered on the symbolic > expression case, not the explicit one-variable function case. I might > be remembering incorrectly, though. No, I think you're right, but the current behavior is the same in both cases. Also, note that the deprecation on integrals ignores this distinction - again, wrongly, in my view. - kcrisman -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
