I have just been researching something similar for string slices. I found this RFC: [https://github.com/nim-lang/RFCs/issues/12](https://github.com/nim-lang/RFCs/issues/12) which lead me to this issue: [https://github.com/nim-lang/RFCs/issues/178](https://github.com/nim-lang/RFCs/issues/178). Right now openarray is the only method to do this, but better approaches are coming soon.
