[Rails] modules

module ActionView
module Helpers
module FormHelper
def form_for(foo, bar)
instantiate_builder(foo, bar)
end
def instantiate_builder(foo,bar)
self
end
end
end
end

"self" in instantiate_builder refers to
ActionView::Helpers::FormHelper. self it will have access to methods
in ActionView::Helpers (its parent module), correct?
