Bottom line, <> won't help you!
I can think of ways of piping through ARGV but, really, you don't
want to go there - believe me.
Some points to help you.
- Perl is very good at guessing what you want, but I don't
think reading from a pipe is ever one of its options
- Piping is often a bad way of doing something that Perl
will do much more easily
- There are many, like me, who will enjoy plumbing the depths
of their knowledge in a particular direction which may be of
no use to you
- It's far better to describe your problem to the list than to
ask how to implement your solution. Think "My wife hates me!"
as opposed to "Where do I get Vallium?"
