[Erica Sadun]

The advantage in going with a "only allow a single member of type T that initializes across the entire tuple" is that it enforces safety and simplicity.

If we want to spin it off into a separate proposal, I think that the most logical split is to have a proposal for subscripts on uniform tuples, and a a proposal for the shorthand syntax and a way to initialize values of these types.
