Use struct identifiers in comments before the value. This has some advantages: - The struct identifiers didn't mix well with other code-comments, where other comments were wrapped onto the next line. - Minor changes could re-align all other comments in the struct. - PyVarObject_HEAD_INIT & tp_name are no longer placed on the same line. Remove overly verbose comments copied from PyTypeObject (Python v2.x), these aren't especially helpful and get outdated. Also corrected some outdated names: - PyTypeObject.tp_print -> tp_vectorcall_offset - PyTypeObject.tp_reserved -> tp_as_async
