def capture(*args)
  value = nil
  buffer = with_output_buffer { value = yield(*args) }

  return buffer.to_s if buffer.size > 0
  value # this applies for "Beachparty" string-only statements.

#concat(string) ⇒ Object

  @output_buffer << string

#content_tag(name, content_or_options_with_block = nil, options = nil, escape = false, &block) ⇒ Object

Below: Rails specific helper fixes. I hate that. I can’t tell you how much I hate those helpers, and their blind escaping for every possible string within the application.

  "#{form_tag_html(html_options)}" << content.to_s << "</form>"
end

#render_template ⇒ Object

This is to prevent multiple renders to share the same output_buffer. I am still trying to find a way to avoid output buffers.

#tag_options(options, escape = true) ⇒ Object

We do statically set escape=true since attributes are double-quoted strings, so we have to escape (default in Rails).
