Hello, All:

I've looked around for an answer to this (The Camel Book, The Ram Book, 
perldoc, google.com, etc.) but can't find a thing: Is it possible to test 
for the existence of a filehandle?

I've got a small script that <optionally> opens a filehandle. If that 
filehandle exists, I'd like to print to it. Otherwise, don't. e.g.,

use Getopts::Std;
getopts("n");
open(OPT_LOG,">/tmp/foo.txt") if ($opt_n);
while (<>) {
        print OPT_LOG $_ if OPT_LOG;
}
close(OPT_LOG) if OPT_LOG;
