You can of course also wrap it in a helper[1] method of your own as
well, to get rid of the ugly. For example:

  def echo(value)
    _erbout << value.to_s
  end

then later in your template:

  <% echo "Hi!" %>

[1] If you take "helper" there literally in the rails sense, you
probably want it in your application_helper.rb file; the same can
apply for any ERB usage using "helper" in a more general sense,
however.
