I was just reading the perldoc on the open (perl 5.8.0) command and noticed the anonymous temp file. 
...
File handles can be opened to "in memory" files held
in Perl scalars via:

     open($fh, '<', \$variable) || ..
...
I was wondering if it was possible to do the same with IO::File. I've tried 
use IO::File;

$var = <<EOT;
line 1
line 2
line 3
EOT

###open($fh, '<', \$var) || die $!; # this works #
$fh = IO::File->new('<', \$var) || die $!; # but this does not #
while ($line = $fh->getline()) {
   print $line;
}
$fh->close();

But it does not work.
The error I get is

IO::Handle: bad open mode: SCALAR(0x11eabc) at test.pl line 10

I've read through the perldoc on IO::File and IO::Handle but can find nothing that indicates that this feature is supported.
Is it possble?
