I learned something. THANKS Corion!
I would not have thought that: while(<>) would try to open a command line arg as a file! But evidently it will!

C:\TEMP>cat corion.pl
#!/usr/bin/perl -w
use strict;

while (<>)
{ print $_;}

C:\TEMP>perl corion.pl a b c
Can't open a: No such file or directory at corion.pl line 4.
Can't open b: No such file or directory at corion.pl line 4.
Can't open c: No such file or directory at corion.pl line 4.
