--- Comment #1 from Jan Jurzitza <d.bugs@webfreak.org> ---
`std.algorithm:cache` could be used, but that still evalutes .front one time too many compared to when `until` should stop when No.openRight is passed in as argument, e.g.

```
iota(10).map!logAccess.cache.until(5, No.openRight).array;
```

will call logAccess on 0, 1, 2, 3, 4, 5 and 6
