If the connection between <> and @ARGV caught you by surprise, I'm afraid you haven't been reading very carefully.

And <> doesn't read from the files in @ARGV when there's nothing on stdin. It's the other way around. It reads from stdin only when @ARGV is empty (or contains "-").

    Well, I went and looked at the Camel book again, and (to my surprise) the behaviour was documented. So yes -- I was not reading carefully, but...

    I still think I wasn't out of my mind to be surprised. The only things I've used the angled brackets for are reading from file handles and globbing. The connection between <> and @ARGV doesn't seem obvious to me. It's a special-case behaviour.

    I've only been w/ Perl for 1.5 years. Give me time. :)

      Sorry if I came off as being snippy. It's just that the use of <> and @ARGV is so common in just about every text-oriented Perl script ever written.... I was just surprised that your experience was so atypical. It's as if C programmer were surprised to find that if you're in a while, and you do a return, it gets you out. (BTW, that was a real question from a real former cow orker. He's probably writing VB these days.)
