Often times you'll see the following pattern for reading and writing to storage slots:

struct Slot {
  address value;
}

...

function getSlot(bytes32 slot) returns (Slot storage s) {
   assembly { s.slot := slot }
}

What exactly is the benefit of this? getSlot(_IMPL_SLOT).value = addr is convenient, but couldn't you also just use a simple setter:

function setSlot(address addr) {
  assembly { 
    sstore(_IMPL_SLOT.slot, addr)
  }
}

What's the benefit of the struct abstraction?
