in reply to return value of chomp is false?

You're trying to be too clever (edit: in that you likely don't need the return value of chomp):

my $names = join '|', map { chomp; $_ } <STDIN>;

    That's what I tried first, but that returns (1,$_) for each value of $_

      Not it doesn't. I suspect you used a comma instead of a semi-colon.

      By the way, there's also 

      use List::MoreUtils qw( apply );
my $names = join '|', apply { chomp } <STDIN>;

      and 
      use Nested::Loops qw( Filter );
my $names = join '|', Filter { chomp } <STDIN>;
