    (a) the following in my class where the instance variables are:

      # Support templating of member data.
  def get_binding
    binding
  end

    (b) also when calling “run” on the ERB object have to pass the result from this method, e.g.

    rhtml = ERB.new(erb_str)
html = rhtml.run(get_binding)
