From the perlfunc::open section of the site(aslo the perl manpages):
If EXPR is omitted, the scalar variable of the same name as the FILEHANDLE contains the filename.
That means that if an open is called like open 0 then 0 is the filehandle, and the "scalar variable" to open. Take, for instance, this example from perlfunc::open:
$ARTICLE = 100; open ARTICLE or die "Can't find article $ARTICLE: $!\n"; while (<ARTICLE>) {...
If your asking why, as in why is it that way, I'd presume its for brevity and ease, as in:
$LOG = '/path/to/log/file/'; open LOG;

    It's probably one of those assume-for-you shortcuts that either didn't take off, nobody remembers anymore, or is from one of the source lanauges.
