This memblock permission will have the same read/write and lifetime modalities as the memblock permission containing this pointer shape, unless they are specifically overridden by the pointer shape; i.e., we have that `[l]memblock(rw,off,len,[l']ptrsh(rw',sh)) = [l]memblock(rw,off,len, fieldsh([l']memblock(rw',0,len(sh),sh)))`, where `rw'` and/or `l'` can be `Nothing`, in which case they default to `rw` and `l`, respectively. |
