Got it! I guess they could also just allow us to use bracket
notation to do the same thing. So something like:
```d
foreach (i; 0 .. list.length) {
(cast(int*)ptr[i]) = i;
}
```
This is what happens with arrays anyways. And arrays ARE
pointers to a contiguous memory block anyways so they could do
the same with regular pointers. The example also looks more
readable.
You can use bracket notation with pointers. You just need to move
your closing parenthesis a bit.
Assuming that `ptr` is a `void*`, these are all equivalent:
```d
(cast(int*) ptr)[i] = whatever;
*((cast(int*) ptr) + i) = whatever;
*(cast(int*) (ptr + i * int.sizeof)) = whatever;
```
