## Other functions

You can add other functions to `os` module via normal binding if you need them.
For example, add `os.system`:

```cpp
PyVar mod = vm->_modules["os"];

vm->bind(mod, "system(cmd: str) -> int", [](VM* vm, ArgsView args){
    const char* cmd = py_cast<CString>(vm, args[0]);
    int code = system(cmd);
    return py_var(vm, code);
});
```
