We now have an explicit AST constructor for arbitrary-size tuple values.
Tuple types are formalized as a type constructor that takes a list
of types as an argument:
data TypeList : sort 1 where {
TypeNil : TypeList;
TypeCons : sort 0 -> TypeList -> TypeList;
}
primitive Tuple : TypeList -> sort 0;
Additional primitives allow constructing and deconstructing tuples
in a nested fashion:
primitive headTuple : (t : sort 0) -> (ts : TypeList) -> Tuple (TypeCons t ts) -> t;
primitive tailTuple : (t : sort 0) -> (ts : TypeList) -> Tuple (TypeCons t ts) -> Tuple ts;
primitive consTuple : (t : sort 0) -> (ts : TypeList) -> t -> Tuple ts -> Tuple (TypeCons t ts);
