You're right.  I see a strange behavior of a slice like
@{$r}[1..2] in scalar subroutine context.  Besides, there is an off-by-one
error in the protection which avoids addressing out-of-bounds.

Mail::Box sub message() should be modified a little:

    if(@_==2)   # range
    {   my ($begin, $end) = @_;
        $begin += $nr   if $begin < 0;
        $begin  = 0     if $begin < 0;
        $end   += $nr   if $end < 0;
 -      $end    = $nr   if $end > $nr;
 +      $end    = $nr-1 if $end >= $nr;
                                                                                
 -      return $begin > $end ? () : @{$self->{MB_messages}}[$begin..$end];
 +      return () if $begin > $end;
 +                                                                              
 +      my @range = @{$self->{MB_messages}}[$begin..$end];
 +      return @range;
    }

Thanks for the report!
