We discussed that earlier outside of mailing list, and I even tried to implement that idea and spent a couple of days to prove that it's not possible. The problem is that the list of atoms is made dynamically, and we can't store pointers to any values in each atom. That's why we need separate cat_file_info variable that is outside of main atom list. We also need is_cat_file because we still have some part of logic that is different for cat-file and for all other commands, and sometimes we need to know that information. > > -Peff
