# Problem: the Hash::slice method in ActiveSupport works a little differently than in Facets. 
# And because Facets is overrides ActiveSupport version this causes problems (for example in to_json method)
# In ActiveSupport it returns :nil if there's no key in Facets it raises error.
# 
# Use Case:
# hash = {:items=>[], "slug"=>"item-z8w", "name"=>"Item", "created_at"=>"2011-01-10T07:04:01Z", "dependent"=>"false", "viewers"=>["manager", "user:user1"], "updated_at"=>"2011-01-10T07:04:01Z", :icon_url=>"null", "text"=>"null", "tags"=>[], "owner_name"=>"user1", "_type"=>"Selector"}
# args = ["id", "_type", "slug", "name", "text", "tags", "dependent", "owner_name", "viewers", "created_at", "updated_at"]
# hash.slice *args
#
# Solution:
# Redefining :slice the same way as in ActiveSupport.
# 
class Hash
  def slice(*keep_keys)
    hash = {}
    keep_keys.each do |key|      
      # hash[key] = fetch(key)
      hash[key] = self[key]
    end
    hash
  end
