output:
```
map[desc:RGB colors:[red green blue]]
map[desc:CMYK colors:[cyan magenta yellow black]]
```

likewise, increasing depth level to `3` yields:
```
red
green
blue
cyan
magenta
yellow
black
```

optionally, kev:value pairs can be emitted as an individual struct:
```go

engine = create_engine(sqlite_url, connect_args=connect_args)


def create_db_and_tables():
    SQLModel.metadata.create_all(engine)


def get_session():
    with Session(engine) as session:
        yield session


SessionDep = Annotated[Session, Depends(get_session)]
app = FastAPI()


@app.on_event("startup")
def on_startup():
    create_db_and_tables()

    @DisplayName("available() on SMB1 returns 0 and marks closed on disconnected statuses")
    void available_smb1_disconnectedStatuses(int status) throws Exception {
        // Verify SMB1 path: disconnected/server-closed statuses yield 0 and mark fd closed
        SmbPipeInputStream stream = newStreamWithInit(false);

        when(handle.ensureOpen()).thenReturn(fd);
        when(fd.getTree()).thenReturn(tree);

2. Al usar un bloque `with`, nos aseguramos de que el objeto similar a un archivo se cierre después de que la función generadora termine. Así, después de que termina de enviar el response.
3. Este `yield from` le dice a la función que itere sobre esa cosa llamada `file_like`. Y luego, para cada parte iterada, yield esa parte como proveniente de esta función generadora (`iterfile`).
