Allow to give an object's method name as symbol define collection

[kriom]

Hi,

I would like to be able to give a method as symbol for the collection
with, for example

class User
  #...
  def locales
    [:"en-US", :"fr-FR", :"es-ES", :"ja-JP", :"zh-CN"]
  end
  #...
end

I would like to do that in my view

form.input(:locale, collection: :locales, include_blank: false)

rather than :

form.input(:locale, collection: form.object.locales, include_blank: false)

Is it feasible? ?
