Subject: !x.include? y

basically, I need to filter list A to match list B. list A is a list
of objects with a particular field, and list B is a list of acceptable
values for that field.

what I have works but it reads sort of clumsily. I changed the ! to a
not and got something slightly more readable:

list.reject! {|thing| not list_of_acceptable_values.include? thing.attribute}

is there a nicer way to do it?
