Hey there, `doctrine/collection` started to introduce generics and stuff. I actually get some issues from this doctrine plugin as it overrides the non-stub types. I'll have a look into this when I find some time, just want to raise the issue to keep track of it. Thanks. ---- Refs: [doctrine/collections v1.7.0](https://github.com/doctrine/collections/releases/tag/1.7.0) https://github.com/doctrine/collections/blob/07d15c8a766e664ec271ae84e5dfc597aeeb03b1/lib/Doctrine/Common/Collections/Collection.php#L27-L30 https://github.com/doctrine/collections/blob/07d15c8a766e664ec271ae84e5dfc597aeeb03b1/lib/Doctrine/Common/Collections/Selectable.php#L17-L18
