Fellow monks,

I have a need to read N files one line at a time and then manipulate those individual lines depending on their content. I was hoping to do something like this

use strict;
use warnings;
use English;

print "Usage: $0 output input1 input2 ...\n";

my $outfile = shift @ARGV;
open(OUT, ">$outfile") || die "Can't open $outfile for writing: $!\n";

my @infile;
foreach (@ARGV) {
   open(IN, $_) || die "can't open $_ for reading: $!\n";
   push @infile, \*IN;
}

foreach(@infile){ 
   my $i = <$_>;
   print "Got: $i";
}

where the @infile array contains all the open file handles so I could read from each one individually. Unfortunately, my test loop at the bottom seems to only read the contents of the last input file specified on the command line. I have this nagging feeling that my problem has something to do with closures (a concept I do not completely comprehend yet). What am I doing wrong?
