I have a function that returns a hash reference. I want to get a slice of the returned hash reference without using a temporary variable. But it seems to be very tricky. This does not work: 

sub x { return {qw(a b c d)}; }
print @{%{x()}}->{"a","b"};

While this does: 

sub x { return {qw(a b c d)}; }
print %{x()}->{"a"};

How would I get a slice?
