* op_static Whether or not the op is statically defined.
* This flag is used by the B::C compiler backend
* and indicates that the op should not be freed.
- * op_spare Five spare bits!
+ * op_latefree tell op_free() to clear this op (and free any kids)
+ * but not yet deallocate the struct. This means that
+ * the op may be safely op_free()d multiple times
+ * op_latefreed an op_latefree op has been op_free()d
+ * op_spare three spare bits!
* op_flags Flags common to all operations. See OPf_* below.
* op_private Flags peculiar to a particular operation (BUT,
* by default, set to the number of children until
