It would really make life easier for new developers. It takes so much time trying to figure out n_pos_args, scope_flags etc and a simple comment would save dozens of minutes.
typedef struct _bytecode_prelude_t {
uint n_state;
uint n_exc_stack;
uint scope_flags;
uint n_pos_args;
uint n_kwonly_args;
uint n_def_pos_args;
uint code_info_size;
} bytecode_prelude_t;
