1) #to_s should always return a string.
2) Any string representation will always be a truth value.

The same situation exists for false:
!!false.to_s  #=> true

You are correct that "" != nil, but "nil" != nil also.
What are you really trying to achieve? And, did you know that
nil.inspect yields "nil"?
