Hi Todd,

this does not work. For example, see here is a line of perl code:

  print "Hello, Rinaldo";

So what is $] in this line and how do you find out? If you simply run
it, you make a decision, with which interpreter you start it. And hereby
you influence the outcome for $]. So: the value of $] is a result of
your decision, not something intrinsic to the code.
