| [`java.nio.file.Path`] implements `Iterable<Path>`, and provides an iterator |
| over the name elements of the path. Declaring a parameter of type |
| `Iterable<Path>` is not recommended, since it allows clients to pass either an |
| `Iterable` of `Path`s, or a single `Path`. Using `Collection<Path>` prevents |
| clients from accidentally passing a single `Path`. |

| Example: |
| |
| ```java |
| void printPaths(Iterable<Path> paths) { |
| for (Path path : paths) System.err.println(path); |
| } |
| ``` |
| |
| ``` |
| printPaths(Paths.get("/tmp/hello")); |
| tmp |
| hello |
| ``` |
| |
| ``` |
| printPaths(ImmutableList.of(Paths.get("/tmp/hello"))); |
| /tmp/hello |
| ``` |
