[Courses] [Perl] Part 2: Scalar Variables

In fact, I think it would be better to wait 24 hours or so before 
sending your answers, just to give everyone a chance to think things 
over, regardless of time zone. Don't hurry for me, because I don't read 
my e-mail on weekends (which I know is unusual for a programmer.  :-)  )

But your answers are right on. This one is particularly insightful:

> Considering that the program output was SuzySuzySuzySuzy, the "x"
 > operator seems to concatenate a string with itself, as many
 > times as asked for (don't know if there is a proper english term
 > for that, but that operator is cool!)

 > outputs "3333". So operands need to be ordered.

  things in different ways, that natural languages accommodate many
  mindsets, and that programming languages should too.
