[DFW.pm] Homework for the list, and for Oct 08 meeting

[Patrick R. Michaud]

Note that MAIN can be a multisub.  In other words, you can do:

  multi sub MAIN(Int :$end = 100, Int :$fizz = 3, Int :$buzz = 5) 
  { 
     ...
  }

  multi sub MAIN(Bool :$help)
  {
    say qq:to"END_USAGE";
    ...
    END_USAGE
  }


Perl 6 will select the MAIN() sub based on the options provided on the command line.
