Here's my reason for wanting it deprecated. It's fragile in the face of unexpected input (I don't like being lulled into a false sense that my code works when suddenly it wouldn't work for a constant input): sage: f=x sage: # many lines of code sage: integrate(f) x^2/2 sage: f=1 sage: # many lines of code sage: integrate(f) # what does this mean? ... hangs maxima ... sage: integrate(f,x) # what does this mean? Now, the fact that the "integrate(1)" hangs maxima is probably a bug all it's own. -- Joel --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
