Re^2: Iterator to parse multiline string with \\n terminator

[three18ti]

What exactly makes it not a closure? Is it that I'm passing a variable each time? If it was a new copy of $fh, wouldn't $fh_iterator->($fh) always return the same line (since it's creating a copy of the $fh object, on next passing it would be a copy of the original)?

Thanks for setting me straight, I always like learning new things.
