@ -1020,7 +1020,7 @@ class A
class_attribute :x, :instance_reader => false
end
A.x = 1 # NoMethodError
A.new.x = 1 # NoMethodError

For convenience +class_attribute+ also defines an instance predicate which is the double negation of what the instance reader returns. In the examples above it would be called +x?+.
