Re: Scalar function

If $fa, $fb, and $fc are file handles, then

print CSV $_, scalar <$fa>, scalar <$fb>, scalar <$fc>;
[download]

is doing the equivalent of

  my $line_a = <$fa>;
  my $line_b = <$fb>;
  my $line_c = <$fc>;

  print CSV $_, $line_a, $line_b, $line_c;
[download]

Note that there is no chomp on the reads from the three files.
