Re: array of arrays to hash

This works too:

my $ranksUsed = [ [ 1 ], [ 2 ] ];
  # No intermediate array or loop...
my %ranksUsed = map {$_->[0] => undef} @$ranksUsed;
[download]

Produces:

$VAR1 = {
          '1' => undef,
          '2' => undef
        };

This has the advantage, IMHO, that it produces the same result as the OPed code in the case that the array or any sub-array(s) are empty.	[reply]
