readdir question

Hi,

this is a working code snippet:

opendir (DIR, $dir) || die "Open failed: $!\n";

$\ = "\n";
while ($_ = readdir(DIR)) { print; };

But when I try to use

while (readdir(DIR)) ...

my script writes only empty lines. It seems that the proper number of
empty lines are written. Does the prepended $_ change readdir's
calling context? Or any other explanation?
