Yay. A generalised form of the input operator, which can create even
handier idioms for simple file processing. Maybe I wasn't clear
enough. My issue wasn't specifically with '.lines' for filter
behaviour -- as a replacement solely for the while (<>) { ... } idiom,
it would be quite adequate. But as a replacement for <OPENEDFILE>, it
is (IMO) sub-par, and definitely does add to the length of the whole.
As for the "nuclear blackmail" argument: One of the prime reasons I
like Perl is that different things look different. When everything
starts looking like a method call, that distinction rapidly drops
away.

Huh. That's really kinda neat.

Which is really short for 'for [EMAIL PROTECTED] {...}', then?
