Hi, In the code below, I'm trying to get a random element from a hash of arrays, given some_number. 
1 my %hoa = (
2   10 => [ "fred", "barney" ],
3   20 => [ "george", "jane", "elroy" ],
4   30 => [ "homer", "marge", "bart" ],
5 );
6 my $ary = $hoa{$some_number};
7 return $ary->[rand @$ary];

I've a feeling line 6 is redundant. Can get pick the random value without first storing the array reference in line 6 i.e. can lines 6 and 7 be done in a single step? Thanks for reading.
