AR has_one association broken?

[agency-morizo]

In 1.0.0, the following in lib/active_record/acts_as_relation.rb (line 65) breaks using AR 3.2.13:

            singleton.send :define_method, :included do |base|
              base.has_one name.to_sym, scope, has_one_options

has_one accepts two arguments, so this raises an ArgumentError (wrong number of arguments (3 for 2)).

1.0.0 depends on AR >= 4
for AR < 4 you have to stick with gem 'acts_as_relation', '~> 1.0'
