```ruby

  class InlineTemplate #:nodoc:
    include Renderable

    # Count the number of inline templates
    cattr_accessor :inline_template_count
    @@inline_template_count = 0

      @view = view

      def method_name_path_segment

      end
  end
end
```

Use the inline template's hash as a method key instead of relying on a counter
