| // single provisioner. |

| // Unlike usual factories, the exact same instance is returned for each call |
| // to the factory and so this must be used in only specialized situations where |
| // the caller can take care to either not mutate the given provider at all |
| // or to mutate it in ways that will not cause unexpected behavior for others |
| // holding the same reference. |
