Re^2: Help understanding a single line of perl: my $count = $row[0] ? $row[0] : 0;

Well, it's probably closer to:

my $count = do {
  if ($row[0]) {
    $row[0];
  } else {
    0
  }
};

but that's less readable to the uninitiated than what you have. :-P

`if` already returns the right thing. It's simply a parser check that prevents it from being used as an expression. (But I guess you know that.) I would have used `do` if it would have made it equivalent, but since it didn't, it was more readable to explain `do` rather than using `do`.	[reply] [d/l] [select]
