## Example

```python
>>> import typing as t
>>> from libtmux.common import tmux_cmd
>>> from libtmux.constants import OptionScope
>>> from libtmux._internal.sparse_array import SparseArray
```

## Example

```python
>>> class MyServer(OptionsMixin):
...     socket_name = server.socket_name
...     def cmd(self, cmd: str, *args: object):
...         cmd_args: t.List[t.Union[str, int]] = [cmd]
...         if self.socket_name:
...             cmd_args.insert(0, f"-L{self.socket_name}")
...         cmd_args.insert(0, "-f/dev/null")
...         return tmux_cmd(*cmd_args, *args)
...
...     default_option_scope = OptionScope.Server
```

```python
>>> MyServer().set_option('escape-time', 1250)
<libtmux.options.MyServer object at ...>
```
