Try it Both Ways

     for my $rn (1..5) {
       $rounds->{"round$rn"} = 
         { player   => $page->param("round${rn}_x"),
           computer => $page->param("round${rn}_o"),
         }
     }

My first cut at this looked different:

     $rounds = { map {("round$_" => 
                           { player   => $page->param("round${_}_x"),
                             computer => $page->param("round${_}_o"),
                           }
                       )} (1..5) };

I tried it both ways
The for loop was much clearer
- (map had too many parentheses)
Don't be afraid to Try it both ways
