-/// | Hint | zsh | fish[^1]|
-/// | ---------------------- | --- | ------- |
-/// | `AnyPath` | Yes | Yes |

-/// | `CommandName` | Yes | Yes |

-/// | `CommandWithArguments` | Yes | |
-/// | `Username` | Yes | Yes |
-/// | `Hostname` | Yes | Yes |
-/// | `Url` | Yes | |
-/// | `EmailAddress` | Yes | |
-///
-/// [^1]: fish completions currently only support named arguments (e.g. -o or --opt), not
-/// positional arguments.
