That's not what I meant. I didn't test this, but try ```Rails.cache.write("lolol", "__nil")```. What I'm saying is that the next ```Rails.cache.read("lolol")``` will return ```nil``` instead of the string ```"__nil"```, which is what I put in :-)

It's not a huge deal. Nobody is gonna ever want to cache the string ```"__nil"``` in practice. But I still think it's not very clean.
