Phew, this got a little more complicated than I hoped. To make this 
understandable I'll just explain the problem. I want a method that 
accepts a block. Inside the method I'm using the method fields_for that 
also accepts a block. I want the f object provided by fields_for passed 
over to the block that MY method accepts, like this:

fields_for_setting("site", "name") do |f|
#--------------------------------------^
#This should be the f object that fields_for provides.
  = f.text_field :value, :index => nil

I simply want to reuse the f object to make my view shorter and cleaner. 
Both in the method where the fields_for is used and in the view, where 
it should be reused.
