+- [#29](https://github.com/zendframework/zend-session/pull/29) extracts the
+  constructor defined in `Zend\Session\Validator\ValidatorChainTrait` and pushes
+  it into each of the `ValidatorChainEM2` and `ValidatorChainEM3`
+  implementations, to prevent colliding constructor definitions due to
+  inheritance + trait usage.
