it doesnt 'quit' if you mean by that exit the program or cause an error...
if you run under -w it will tell you you might have made a mistake by not
opening the filehandle... you could do a check if it's open of course but
that's not what you want most likely

you can make an easy check for that if you like:
my $debug = 1; (or '' if you want to turn muy verbose off)
and with that you can build in statements like this:
$debug && print "extra verbose msg!";
this will only print if $debug has a value
Hope this helps,
