Implement .html_safe by delegating it to the resulting string
user
```ruby
# -*- encoding : utf-8 -*-

        alias :tableize :to_s

        # Delegate .html_safe from accessing Delegate object as if it was a hash,
        # but instead perform it on the resulting string
        delegate :html_safe, to: :to_s

        def self.log(message)
          message = "phrase: #{message}"
