Rails Ruby on Rails

A quick look at the current code for reference...

# File actionpack/lib/action_view/helpers/capture_helper.rb, line 38
def capture(*args)
  value = nil
  buffer = with_output_buffer { value = yield(*args) }
  if string = buffer.presence || value and string.is_a?(String)
    ERB::Util.html_escape string
  end
end

Let's say I have a block that includes JSON, like if I call #to_json on a Hash, and pass that into capture. Then, that string gets #html_escape'd TWICE. The result is impossible to deal with once you get a few layers into it. Should capture take a option[:no_escape]? Or, have an entirely separate method to call, like, #capture_without_escaping? The latter approach is what I've been doing in the ApplicationHelper of my applications. I'd write a patch file, just want to hear some thoughts on a best-practice for this.
