Is the GiNaC development team making a habit out of ignoring patches? I realize that because of adding a new overloaded version of rename_dummy_indices_uniquely this probably can't go into 1.3.3 but the separate symmetrization of different index types could have gone into it, I think. Also, I would appreciate it if changes were added to the 1.4.0-branch. This spares me the trouble of managing a locally changed version of GiNaC. Here is the latest diff of my local copy of GiNaC with the CVS tree. New changes are: (1) Made an automatic symplification that turns an indexed object without indices into its op(0). This is because it is sometimes useful to make an indexed object out of an exvector and an indexed object without indices is quite silly, really. (2) Made the return_type and return_type_tinfo of an indexed object return these values as they are of op(0). Reason: if the user wants to define his own noncommutative functions/symbols and wants them to take indices, that user probably wants these indexed objects to be noncummutative. Best wishes, Chris
