 The peculiarity of the one-tuple is unfortunate. Couldn't we aim towards
 something like this:
   - Boxed tuple constructors: `()*`, `(**)`, `(*,*)`, `(*,,*)`, etc.
   - Unboxed tuple constructors: `()#`, `(##)`, `(#,#)`, `(#,,#)`, etc.
   - Syntactic sugar: `()`, `(,)`, `(,,)`, etc. default to boxed tuples

 This would avoid the bikeshedding and fix the use of the name "unit" for a
 one-tuple.
