+ * flag; then various places such as av_store() skip mg_set(ary) if this
+ * flag is set, and various magic vtable methods set flags like
+ * DM_ARRAY_ISA if they've seen something of that ilk. Finally when
+ * control returns to pp_push or whatever, it sees if any of those flags
+ * have been set, and if so finally calls mg_set().
+ *
+ * NB: PL_delaymagic is automatically saved and restored by JUMPENV_PUSH
+ * / POP. This removes the need to do ENTER/SAVEI16(PL_delaymagic)/LEAVE
