I'm currently in New Orleans visiting a friend until Thursday, so I'll have less time than normal to look at these, but I'll definitely give it a try. Most of the issue is not the actual conversion, but finding the right order in which to convert functions. For example, the object-id-part8 branch on my GitHub account converts parse_object, but parse_tree_indirect has to be converted before you can do parse_object. That leads to another handful of patches that have to be done. -- brian m. carlson / brian with sandals: Houston, Texas, US +1 832 623 2791 | https://www.crustytoothpaste.net/~bmc | My opinion only OpenPGP: https://keybase.io/bk2204
