Although I wish more than 3 people had voted in my poll, two of 
them did claim to need the `ref`-ness of `Tuple.slice`, so I 
don't think we can just ditch it. (I did not vote.)

If you guys want to add a return-by-value version, it should be 
treated as an enhancement, not a bug fix in my opinion.
