Yes. It does nothing, unless you're running with the -w option, in which
case
it generates a warning.

As long as some other part of your program isn't using the same
filehandle,
yes. For robustness, I would recommend running with -w and using
open(FILEHANDLE, ">/dev/null") || die "Couldn't open /dev/null ($!)\n";
assuming you're on Unix.

Apologies to the htdiggers for polluting this forum with Perliness.
