Hello,

I'm trying to pass an anonymous hash to a sub the laziest way I possibly can. So I'm doing the usual:
get_ids({'id_one' => 1, 'id_two' => 2, 'id_three' => 3})

But what I'd really like to do is something like:
get_ids({'id_one','id_two','id_three'})

[download]

This doesn't seem to work. When I shift the hashref to a scalar in the sub the scalar only knows about the first key id_one when I dereference it using a map:
sub get_ids {
    $id_hashref = shift;
    map { print "key $_ exists in the request\n" } (keys %{$id_hashref
+});
}

Is there a way to pass an anonymous hash to a sub without defining unnecessary values for all of the keys? I could pass an array and make it hash keys in the sub, but I'd really rather not. I have the funny feeling I'm missing something, but its 1am...:)

Thanks,
Alex
