The only way I can think of doing this without heavily restructuring your code is to create a pipe, fork off a child, then have the child write the list of filenames to the pipe and have the parent read them back in.

    ...Which isn't as hard as it sounds. Something like:
    my $f = List->new; my $pid = open(FROM_LIST,"-"); if (!defined($pid)) { die "fork error: $!\n"; } elsif (!$pid) { # Child $f->stream_to(\*STDOUT); $f->look_in('c:/'); $f->list; exit(0); } # Parent while (<FROM_LIST>) { print "$_\n"; }
    should do the trick.
