Example :
posts = Post.scoped
posts.size # Fires "select count(*) from posts" and returns the count
posts.each {|p| puts p.name } # Fires "select * from posts" and loads post objects
I think it may of broke the build. Lets see.
This reverts commit 49e943c4f0.

activerecord/test/cases/associations/has_many_associations_test.rb
add_column and change_column in the Mysql adapter now accept some
additional options:
:first => true # Put the column in front of all the columns
:after => column_name # Put the colmn after 'column_name'
add_column :new_col, :string, :first => true
add_column :another_col, :integer, :default => 0, :after => :new_col

* A new module (ActiveSupport::Autoload) is provide that extends
autoloading with new behavior.
* All autoloads in modules that have extended ActiveSupport::Autoload
will be eagerly required in threadsafe environments
* Autoloads can optionally leave off the path if the path is the same
as full_constant_name.underscore
* It is possible to specify that a group of autoloads live under an
additional path. For instance, all of ActionDispatch's middlewares
are ActionDispatch::MiddlewareName, but they live under
"action_dispatch/middlewares/middleware_name"
* It is possible to specify that a group of autoloads are all found
at the same path. For instance, a number of exceptions might all
be declared there.
* One consequence of this is that testing-related constants are not
autoloaded. To get the testing helpers for a given component,
require "component_name/test_case". For instance, "action_controller/test_case".
* test_help.rb, which is automatically required by a Rails application's
test helper, requires the test_case.rb for all active components, so
this change will not be disruptive in existing or new applications.
In the current stable, ActiveRecord::Associations::AssociationProxy#method_missing calls yield() if a block is given, causing the block to always be evaluated in its calling context. However, in the case of instance_eval, correct behavior requires that the block be passed directly to the @target, rather than being evaluated inside a different block. Incidentally, this also simplifies the code slightly.
