tamaguchi has asked for the wisdom of the Perl Monks concerning the following question:

Suppose you have following data stucture:
my %hash=( 1=> [1.5, 2.1, 3.1], 2=> [1.2, 2.2, 3.2], 3=> [1.3, 2.3, 3.3], )
How would you do in the easiest way to get out an array consisting of the first ellement in each of the internal valuearrays sorted by the keys? I.e. $array[0]=1.5,  $array[1]=1.2 and $array[2]=1.3. Thank you fellow monk.
