in thread arranging the csv file

Marrying your and Loops' approach: 

use strict;
use warnings;

my %data = map { /(.*?)\s*,/ => $_ } <DATA>;
print @data{ qw( 10.1 100.1 25.1 103.1 ) };

__DATA__
100.1,A ,25, 36,56,89,45,36,56
25.1 ,B,232,565,65,56,56,48,25
103.1,C,25,5,6,9,4,5,56,889,9
10.1,D,5,6,5,8,9,8,12,23,36,6

    Question: can anyone do this as a oneliner without a named hash?

    Everybody can :) even you :) , do, references quick reference, hashes are curly 

    $ perl -l - 2
  print @{
          {
            map {   /(.*?)\s*,/ and $1 => $_  }
           <>
          }
        }{ qw/  10.1 100.1 25.1 103.1  / }
__END__

      Actually, I was not able to do it, and I have been experimenting with various types of sigils and parentheses for a while. Many thanks!
