Thanks to both of you! Well, that was a silly of me, eh? In my defense, I'm
going through Thomas/Hunt book (which is excellent) and there are instances
of expressions with their output like aSong.duration --> 257. I thought that
this was all that was required semantically to output to stdout. Thanks for
getting back on track. I'm having a lot of fun with Ruby!
