Inclusion validation fails when provided a symbol instead of a string
===

My model is like:

    class Client < ActiveRecord::Base
      VALID_STATES = %w(active suspended closed)
      validates :status, :inclusion => { :in => VALID_STATES }
    end

Ths validation works fine if the status came from a form (as a string), but i like to do something like:

    @client.status = :active

which throws an error that the status isn't in the list, obviously that's because `%w` doesn't generate an array of symbols too, Is there a work around this without ending up using strings?
