in reply to length or array in a hash

Hi ongaku,

perldoc -f length says that length isn't the right thing to use to find the number of elements in the array (I am assuming here that you're looking for the number of elements in the array). I think something along the lines of scalar @{$hash{one}} might be what you're looking for.
