In-place [`cumprod`](./cumprod.md#cumprod): rewrites `self` with its inclusive prefix products along `dim` and returns it under the value surface, [`Result`](../Result.md)`<void>` under the [`Result`](../Result.md) surface; [`CLIKART_CHECK`](../../index.md#CLIKART_CHECK) is the mode-stable spelling.

**Throws**

- `ClikaRT::Error`: as [`cumprod`](./cumprod.md#cumprod).
