Really quick question. When passing around filehandles between subs, what is the difference between: 
sub one (*) { my $fh = shift; print $fh "$fh (glob)"; }

open (OUTER,"+>out.txt") or die "$!\n\n";
one (\*OUTER);

[download]
and a very slight change: 
sub one (*) { my $fh = shift; print $fh "$fh (glob)"; }

open (OUTER,"+>out.txt") or die "$!\n\n";
one (*OUTER);

As you can see, in the first example it seems that I have passed a glob reference to the sub, while in the second example I have simply passed the glob. Both work exactly the same, yet I have seen both - what is the difference (is one advantageous over the other)?

Also, what is the reason that if I protoype one() like this: 
sub one(\*) { ... }

[download]
it doesn't work, but 
sub one(*) { ... }

[download]
does? I would think that using \* would just require a glob reference - where am I wrong?

Thanks for the help - these glob things are very new to me!
