How about something like this? I'm returning just the second element of the
resulting list of using split() on $_.
This shortcut for getting just one element of a list can be used on any
function that returns a list. Naturally this is not the most efficient method,
so your mileage may vary.

Sure, for instance:
my @column = ();
while (<>) {
my ($field) = (split)[1]; # extract 2n
