Don't think so. This may make a difference, but I don't think it
would in this case.
I tried Harhs's code with a recently installed XML::Atom::Syndication
0.08 and it seems to work fine. Exactly the same results without and
with the braces.

P.S.: Explanation for those new engough to Perl:
The braces change the context in which the $atomic->get() method is
called. In the first case it's called in scalar context, in the
second in list context. The method may test for the context using the
wantarray() builtin and return different results in each case:
my $x = localtime();
print "$x\n";
vs.
my ($x) = localtime();
print "$x\n";
The result may be different even without the method testing it
directly. If the return statement looks like this:
return @array;
then in scalar context you'll get the number of elements in the array
and in list context you'll get the contents. In which case the
behaviour could be 1 in scalar context and the object in list
context:
sub foo {
my @arr = ('obj');
return @arr;
}
my $x = foo();
print "$x\n";
my ($x) = foo();
print "$x\n";
Doesn't seem to be the case with XML::Atom::Syndication.
