Aside from the failing checks (not sure why they failed) is there any reason this hasn't been merged in yet, @richardm-stripe?

We're aiming to add support for PHP 8.1 in the coming weeks and this will be one fewer package that I have to fork and maintain in order to add the attributes required to keep PHP 8.1 happy.

To be clear, the ReturnTypeWillChange attribute will not functionally affect anything and the suggested changes made by @kylekatarnls seem to be correct.

Hello @chrisdeeming, thank you for submitting this. This should have been subsumed by #1211 and #1209, and released in v7.104.0 today, which added the ReturnTypeWillChange annotation to all the appropriate locations.

Hi @richardm-stripe,

This should have been subsumed by #1211 and #1209

seems that a few were missed so I've created #1213 to add them. Looking forward to have those added too! Thanks.
