You can also just say @x, here, because puts will convert the objects it
receives into strings by calling the to_s method on them
puts "#{@x}"
puts @x.to_s
puts @x

In this case will all be the same, there is no need to interpolate strings
here.

At least in 1.9.1 this is true. I tried it in 1.8 and the last one outputted
"nil" which is odd, and the only way I can think of that would explain it is
that puts checks to see if the variable is nil before calling to_s, and
explicitly outputs "nil" if it is.
