--- members
-- @section members

  --- evaluate this AST Node.
  --
  -- Evaluate this node and return a `RTNode`.
  --
  -- @function eval
  -- @tparam Scope scope the scope to evaluate in
  -- @treturn RTNode the evaluation result

  --- create a clone with its own identity.
  --
  -- creates a clone of this Cell with its own identity by prepending a `parent`

  --- stringify this AST Node.
  --
  -- Should return the exact string this node was parsed from (if it was parsed).
