P.S. The point of the example was to show how nesting isn't necessary 
much of the time. The authors wanted to show that it is okay to write a 
call to f2 before f2 is even defined, as long as f2 is defined before 
that call is actually executed, i.e. when f1() is called. Keeping the 
two functions separate is cleaner than nesting, and passing parameters 
is how you get around the local scope issue.
