Greetings fellow monks,

I need to parse a file that can include other files (which can include other files, etc). I think the easiest way to handle this would be recursion but I'm not sure how well perl handles opening a filehandle with the same reference. To clarify:

sub get_hosts {
my $file = shift;
open (HOSTS, <$file) or die("I can't open $file");
while (<HOSTS>) {
   if ( /^include (.*)$/ ) get_hosts($1);
   &parse_line;
}
close HOSTS;
}

Can perl handle this gracefully? If not, what are my options? I can try it and see but thought I'd ask.
