What are you trying to do here?

What you've written is equivalent to

  if p(Y.z)
    0
    osax.say(Y.z)
  end

You haven't defined a method called p, so you get the standard Kernel#p

"p x" is like "puts x.inspect" and returns nil, which is treated as 
false, so the code inside the if is not executed.
