Here is one more elegant Dlang thing where you can use `with` and 
dtors to control an arena:

```d
auto arena = Arena(512);
with (ScopedArena(arena)) {
     make!char('C');
     with (ScopedArena(arena)) {
         make!short(2);
         make!char('D');
         assert(arena.offset == 5);
     }
     assert(arena.offset == 1);
}
assert(arena.offset == 0);
arena.free();
```

Mostly showing this because arenas are really cool and trendy 
right now :)
