Introduce dynamic scopes for ActiveRecord: you can now use class methods like scoped_by_user_name(user_name) and scoped_by_user_name_and_password(user_name, password) that will use the scoped method with attributes you supply. [#1648 state:committed]

To simplify using of ActiveSupport in 3rd party libraries,
a simple way to require only minimum of commonly used extensions
(multibyte, inflections, array and hash extensions, #blank?, and a few
others) is needed. For exactly this reason some out-of-Rails-space
libraries adopted Extlib, originally from DataMapper.

To keep it 2067% backwards compatible, and still available
to everyone even in 2.x releases, active_support/minimalistic.rb
was added.

Use it like this:

gem 'active_support', '>=2.3'
require 'active_support/minimalistic'

instead of

require 'activesupport'

Right now this package with RubyGems uses about 10 megs of RAM
(10.01 or so). It can be further slimmed down though, once we simplify
multibyte implementation that right now uses advanced accessors
from Module extensions.

To compare RAM usage with previous ActiveSupport versions and Extlib,
at the time of writing, see http://gist.github.com/40401.

With self referential associations, the scope for the the top level should not affect fetching of associations, for example
when doing

Person.male.find :all, :include => :friends

we should load all of the friends for each male, not just the male friends.

Marshal.dump(Marshal.load(marshaled_hash)) is not guarenteed to be equal to marshaled_hash
because of the lack of ordering of hash
