        # Fiddle::Pointer.[]=

(from ruby core)
### Implementation from Pointer
---
    ptr[index]         = int                    ->  int
    ptr[start, length] = string or cptr or addr ->  string or dl_cptr or addr

---

Set the value at `index` to `int`.

Or, set the memory at `start` until `length` with the contents of
`string`, the memory from `dl_cptr`, or the memory pointed at by the
memory address `addr`.
