I'm posting anonymously to defeat being voted down...

This is probably really easy. I just don't know how to make this any better: I am trying to make a hash of row references: 

foreach my $row (@$array_ref)
{
  $hash{$row->[0]} = $row;
}

[download]
Where $array_ref is a pointer to a two-dimensional array. Does anyone know a one liner that would do this? Thanks in advance .... :o)
