A couple of quick examples may make it easier to understand what a hash slice is doing. This code:

@hash{"one", "two", "three"} = 1 .. 3;
[download]

Is equivalent to:

($hash{one}, $hash{two}, $hash{three}) = 1 .. 3;

And likewise, these are equivalent:

my @list = @hash{"one", "two", "three"};
[download]

and

my @list = ($hash{one}, $hash{two}, $hash{three});
