I'm not sure actually. The way I look at it, built-in tuples are quite 
low-level (types can't be spelled, automatic expansion and flattening, 
undecided first-class semantics) and should seldom be dealt with 
directly. The best use of built-in tuples is in the implementation of 
truly well-behaved, composable tuples.
