      .has(Name.where(_.endsWith("1")))
.has(Name.where(_.matches("[LR].")))
.has(Name.where(P.eq("R1")))
.has(Name.where(P.neq("R1")))
.has(Name.where(P.within(Set("L1", "L2"))))
.has(Name.where(P.within("L1", "L2", "L3")))
.has(Name.where(P.matches("[LR].")))
  4. def has[A](key: PropertyKey[A], value: A): Traversal[E]
