No it still works with chomp

To understand why this works, take a look at the return value for chomp. Hint: it's not the string with newlines missing.

The problem with while (my $line = <DATA>) {} is real, it's just obscure. As hinted, it only happens when you get a line with a false value and no newline. Sometimes this happens at the end of a file. Sometimes it happens for other reasons. It usually doesn't cause any actual problems, but certainly is something to look out for.
