Upstream changes:
0.62 Wed November 26, 2008
    * Moose::Meta::Role::Application::ToClass
      Moose::Meta::Role::Application::ToRole
      - fixed issues where excluding and aliasing the
        same methods for a single role did not work
        right (worked just fine with multiple
        roles) (stevan)
        - added test for this (stevan)

    * Moose::Meta::Role::Application::RoleSummation
      - fixed the error message when trying to compose
        a role with a role it excludes (Sartak)

    * Moose::Exporter
      - Catch another case where recursion caused the value
        of $CALLER to be stamped on (t0m)
        - added test for this (t0m)

    * Moose
      - Remove the make_immutable keyword, which has been
        deprecated since April. It breaks metaclasses that
        use Moose without no Moose (Sartak)

    * Moose::Meta::Attribute
      - Removing an attribute from a class now also removes delegation
        (handles) methods installed for that attribute (t0m)
        - added test for this (t0m)

    * Moose::Meta::Method::Constructor
      - An attribute with a default that looked like a number (but was
        really a string) would accidentally be treated as a number
        when the constructor was made immutable (perigrin)
        - added test for this (perigrin)

    * Moose::Meta::Role
      - create method for constructing a role
        dynamically (Sartak)
        - added test for this (Sartak)
      - anonymous roles! (Sartak)
        - added test for this (Sartak)

    * Moose::Role
      - more consistent error messages (Sartak)

    * Moose::Cookbook::Roles::Recipe1
      - attempt to explain why a role that just requires
        methods is useful (Sartak)
