A backwards-compatibility layer has been added to persistence to help
consumers move to the new namespacing. It is based on class aliases,
which means the type declaration changes should not be a BC-break: types
are the same.
See doctrine/persistence#71
This means:
using the new namespaces
adding autoload calls for new types to types that may be extended and
use persistence types in type declarations of non-constructor methods,
so that signature compatibility is recognized by old versions of php.
