Yes, there is a comment in there (the first part added by rws): 716 // The following comment is no longer true for pynac. 717 // We use the print order to determine the main variable 718 // This order is not random. 719 // XXX: The main variable is chosen in a random way, so this code 720 // does NOT transform the term into the canonical form (thus, in some 721 // very unlucky event it can even loop forever). Hopefully the main 722 // variable will be the same for all terms in *this However, the part about "in some very unlucky event it can even loop forever" appears to be true :( That hardly seems ideal. There should be a fix to prevent that from happening. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
