+ * include/ruby/ruby.h: support write barrier protection for T_STRUCT.
+ Introduce the following C APIs:
+ * RSTRUCT_RAWPTR(st) returns pointer (do WB on your risk).
+ The type of returned pointer is (const VALUE *).
+ * RSTRUCT_GET(st, idx) returns idx-th value of struct.
+ * RSTRUCT_SET(st, idx, v) set idx-th value by v with WB.
+ And
+ * RSTRUCT_PTR(st) returns pointer with shady operation.
+ The type of returned pointer is (VALUE *).
+
+ * struct.c, re.c, gc.c, marshal.c: rewrite with above APIs.
