 This RFC proposes the addition of several features to support variadic generics:
 - An intrinsic `Tuple` trait implemented exclusively by tuples
-- `(Head, ...Tail)` syntax for tuple types where `Tail: Tuple`
+- `...T` syntax for tuple types where `T: Tuple`
 - `let (head, ...tail) = tuple;` pattern-matching syntax for tuples
 - `let tuple = (head, ...tail);` syntax for joining an element with a tuple

 other functional programming languages will likely be familiar with the concept

 When teaching this new syntax, it is important to note that the proposed system
 allows for more complicated matching than traditional `Cons`-lists. For example,
