Not to my knowledge.... Though you're not the first one to ask, and it may be sound to implement it eventually ^^; When dealing with graphs, there's a small workaround : store the graph6_string instead of the graph itself... But that's not an acceptable answer ^^; Nathann -- 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
