=== Request/Instance Scope
For every incoming request a new instance of your application class is created
and all handler blocks run in that scope. From within this scope you can
access the `request` or `session` object and call methods like `erb` or
`haml`. You can access the application scope from within the request scope via

The delegation scope just forwards methods to the class scope. However, it
does not behave 100% like the class scope, as you do not have the classes
bindings: Only methods explicitly marked for delegation are available and you
do not share variables with the class scope (read: you have a different
`self`).
