Hi folks :) I know everyone is already quite busy attempting to resolve scalar types, assertions, etc. So let me add another RFC to your pre-feature-freeze cognitive overload! This proposal allows the specification of and access to Generator return expressions:
https://wiki.php.net/rfc/generator-return-expressions The proposed functionality allows for more robust coroutine multitasking and lays the groundwork for the future implementation of the `yield from` sub-generator syntax found in other languages. Please take a few minutes in the coming days to read the proposal and ask any questions you may have as I plan to initiate a vote for inclusion in PHP 7 as soon as the required discussion period elapses. Thanks for your time and thanks to Nikita for writing the patch to make this happen. - Daniel
