Bertand finally beat some sense into me, convincing me that tuples with named elements are more important than tuples with anonymous elements.
This changes the grammar for tuple type elements to be:
 ///   type-tuple-element:
 ///     identifier? ':' type

instead of:
///   type-tuple-element:
///     type
///     '.' identifier ':' type


In practice this means that you don't have to use things like (.x : int, .y : int) you can just use (x :int, y:int) which is what we already have for function argument lists.
