Make sense.
Then, what about using anonymous struct to make GC code more readable?
typedef union _gc_head {
struct {
union _gc_head *gc_next;
union _gc_head *gc_prev;
Py_ssize_t gc_refs;
- } gc;
+ };
double dummy; /* force worst-case alignment */
} PyGC_Head;
All code like g->gc.gc_next will be like g->gc_next.
