| * [*Precondition:] The `value_type` of the range is comparable with `operator==()`. |
| * [*Postcondition:] For all adjacent elements `[x,y]` in the returned range, `x==y` is false. |
| * [*Range Category:] __forward_range__ |
| * [*Returned Range Category:] The minimum of the range concept of `rng` and __forward_range__. |
