sealed abstract class Catenable[+A] extends AnyRef
Trivial catenable sequence. Supports O(1) append, and (amortized)
O(1) uncons, such that walking the sequence via N successive uncons
steps takes O(N). Like a difference list, conversion to a Seq[A]
takes linear time, regardless of how the sequence is built up.
