digamos recebo uma classe e não um objeto como parametro, e neste caso não "funfaria"

def something(klass)
puts klass.bool? ? "bool" : "not bool"
end

something TrueClass # => not bool
something FalseClass # => not bool

sacou?

ruby-1.9.2-p180 :012 > FalseClass.bool?
 => false 
ruby-1.9.2-p180 :013 > TrueClass.bool?
 => false
