I wrote a draft of this & pushed it to my github branch. I converted one file to this approach. Now it looks like: struct arch_object : public PyObject { [...] const char *name () { return gdbarch_bfd_arch_info (require ())->printable_name; } ... }; static PyMethodDef arch_object_methods [] = { noargs_method ("name", "name () -> String.\n\ Return the name of the architecture as a string value."), I wish it could be a little more concise, but I'm not sure it can be without a macro. So maybe this is the way to go. Tom
