  # @todo Changing Parser::AST::Node to AST::Node below will

  #   cause type errors at strong level because the combined

  #   pin for AST::Node#children has return type

  #   "Array<AST::Node>, Array".  YARD annotations in AST

  #   provided the Array, RBS for Array<AST::Node>.  We

  #   should probably have a rule to combine "A, A<T>""

  #   types to "A<T>" if the "A" comes from YARD, with the

  #   rationale that folks tend to be less formal with types in

  #   YARD.
