Dear wise monks!

perldoc -f open explains:

In the 2-arguments (and 1-argument) form opening '-' opens STDIN and opening '>-' opens STDOUT.

I try following code (for perl-5.8.0) but do not succeed: 

$|=1;
my $stdout='';
close STDOUT;
open STDOUT, ">", \$stdout;
print "this\n";
close STDOUT;
open STDOUT, '>-';
print "that\n";
print "[$stdout]";

It does not print anything to STDOUT, while I'm expecting to see output for last two lines.

perl-5.6.1 produces same effect (but it's better to comment a line about opening STDOUT in-memory)
I tried perl on Windows and Linux --- same effect.

What do I do wrong?

Thanks in advance,
Courage, the Cowardly Dog
