Nil is actually NilClass

If for whatever reason you wanted to modify something inside nil, the class name is NilClass

🤯 Yes it's very mind blowing, I know 🤯

Example of bad code I couldn't figure out why it wasn't working

class Nil
  def to_i
    -1
  end
end

The fix needed to make it behave as expected

class NilClass
  def to_i
    -1
  end
end
