A function may also return a `stream<T>` of any other supported type, written as a list of the stream's items. A stream with items must be returned by an `async` function, which writes the items as the caller reads them, then closes the stream. An empty stream, `[]`, may be returned by any function. Calling an `async` function that returns a stream needs a runtime with support for the component model's async features, e.g. Wasmtime with `component-model-async` enabled. ```wit /// @value [1, 1, 2, 3, 5, 8] fibonacci: async func() -> stream<u32>; ``` Signed-off-by: Scott Andrews <scott@andrews.me>
