1/6     If anyone with any Perl 5.004 fu can explain the following behavior
        coherently, I'd be enlightened. The file is located in
        ~god/Pub/perl.bugs
        \_ 1.  The first evaluates the backquote expression in list context
               and stores the first element of the result in $result1.  The
               second evaluates the backquote expression in scalar context
               and stores the entire result, as a string, in $result2.  It
               has nothing to do with your use of "my"; you can (and should)
               rewrite the second as
                  my $result2 = `cp --help 2>&1`;
               See "perldoc perlsub" for more information.
           2.  Both of your examples work fine for me.  Could you elaborate
               on what goes wrong when you try them?
           3.  You can't declare $_ with my.  This is a special case in perl
               which may change sometime; it's mentioned in "perldoc perlsub".
               For now, use local instead of my for $_.
