Of course there is. Those two are different. Notice that the fifth
variable in the list is not a scalar but an array. It is supposed to
slurp all items starting with the fifth. While usually the
gethostbyname() will return only one address it may return several.
At least according to the docs.
Example:
sub foo { (0,1,2,3,4,5,6,6,8,9) };
(undef,undef,undef,undef,@a1) = foo();
@a2 = (foo())[4];
print join(", ", @a1),"\n";
print join(", ", @a2),"\n";

There is a reason for living. There must be. I've seen it somewhere.
It's just that in the mess on my table ... and in my brain
I can't find it.
