So you think localizing @ARGV should also localize the (potentially open) ARGV filehandle too? Maybe I'm not understanding you, but that doesn't make a lot of sense to me.

What exactly did you try? Localizing *ARGV worked for me exactly as I would have thought: 

$ cat ../domk.pl
#!/usr/bin/perl

use strict;
use warnings;

while (<>) {
    chomp;
    print "huzzah:".collect( $_ )."!\n";
}

sub collect {
    local *ARGV;
    @ARGV = @_;
    join '', <>;
}

$ ls file? | ../domk.pl
huzzah:file1 line1
file1 line2
!
huzzah:file2 line1
file2 line2
!
