I think the "and-call" operator discussed recently would be a very very
very nice addition, especially since in Rails Views (or any
presentation layer on most any framework in most languages) has the
ever-so-common "obj ? obj.value : nil" mini-pattern.

Of course it doesn't really apply in this specific case since there's
an empty array available, but:

item.cart_item_option_values &? each do { |ov| blah }

Would be nice.
