In reading this discussion about STDIN, ARGV, and the <> magic
scanner, I had a thought cross my mind, and tried it out.

The command:

    perl -pe '' '|ps' '|who'

printed the output of a ps and a who command!  In processing the
command line arg list as "files" using the <> magic cookie, you
can have all of the magic filename control handling that any
other open provides - pipes, redirection of file descriptors, etc.

Now, to beat Randall to it (if he hasn't already done it a year ago)...

    perl -pe '' '|echo Just' '|echo another' '|echo Perl' '|echo hacker'
