## Return Type and Data Filtering

Let's continue from the previous example. We wanted to **annotate the function with one type**, but we wanted to be able to return from the function something that actually includes **more data**.

    void add(Runnable runnable, Executor executor);

    void execute();
    /** Returns the underlying implementation, useful for the Footprint benchmark. */
    Object getImpl();
  }

  enum Impl {
    NEW {
      @Override
      ExecutionListWrapper newExecutionList() {
        return new ExecutionListWrapper() {
          final ExecutionList list = new ExecutionList();

          @Override

linkage to the desired libraries. The main function is provided by
_cgo_main.c:

	int main() { return 0; }
	void crosscall2(void(*fn)(void*), void *a, int c, uintptr_t ctxt) { }
	uintptr_t _cgo_wait_runtime_init_done(void) { return 0; }
	void _cgo_release_context(uintptr_t ctxt) { }
	char* _cgo_topofstack(void) { return (char*)0; }
	void _cgo_allocate(void *a, int c) { }
	void _cgo_panic(void *a, int c) { }

#### Obtain help for each key

```
~ mc admin config set myminio/ <key>
```

e.g: `mc admin config set myminio/ etcd` returns available `etcd` config args

```
~ mc admin config set play/ etcd
