In my precedent message, I proposed a solution that was not considered maybe because it was in a test context. As a newbie in Perl, I would like to know if my solution is good or wrong. 
  my $fc = substr($str_a,0,1);
  for my $str_b ( @list ) {
    next if ord($fc) == ord((split(//, $str_b))[0]);
    expensive_function ( $str_a, $str_b );
  }
