Yes, it's not particularly difficult with Go either. The default array/list type (slices) can point to unmanaged memory so it's easy to feed unmanaged data directly into most APIs. Also you can directly use off heap objects to support interfaces and pass references to them around just like objects allocated on the Go heap. Of course there are no generics yet so doing things like re-using a custom hash table implementation will be less convenient.
