* 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.
Just a copy from Active Record (with tests). Each is a warpper function for
the equivalent scoped call to find eg first is a wrapper for find(:first)

Similar to Active Record - it will raise ActiveResouce::ResourceInvalid if
the resource is not valid (ie if <tt>valid?</tt> returns false)
However - does not raise ActiveResource::ResourceNotFound if the callbacks
fail (callbacks have not yet been implemented) - it will just try to save
and raise if the callbacks all fail.
This is not ideal behaviour - but will do until we decide to change the
behaviour of save_with_validations to actually raise (rather than catch) the
ResourceInvalid exception.

Active Record does not explode with RecordNotFound if you go looking for a
collection of objects - it just returns nil. Thus Active Resource should
also not explode.
After all - finding no objects that match a set of conditions is not
exceptional behaviour - unlike looking for a specific object with a given id
(which you'd expect to exist).
I've also added documentation to +find+ to reflect this.

Example: ActiveSupport::JSON.backend = "JSONGem"
All internal Rails JSON encoding is now handled by ActiveSupport::JSON.encode(). Use of #to_json is not recommended, as it may clash with other libraries that overwrite it. However, you can recover Rails specific functionality
if you really want to use #to_json.
gem 'json'
ActiveSupport::JSON.backend = "JSONGem"
class ActiveRecord::Base
alias to_json rails_to_json
end
