The method +returning+ yields its argument to a block and returns it. You typically use it with a mutable object that gets modified in the block:
<ruby>
def html_options_for_form(url_for_options, options, *parameters_for_url)
returning options.stringify_keys do |html_options|
html_options["enctype"] = "multipart/form-data" if html_options.delete("multipart")
html_options["action"] = url_for(url_for_options, *parameters_for_url)
end
end
</ruby>

Sometimes you want to call a method provided the receiver object is not +nil+, which is something you usually check first.
