Hi internals, I'd like to present an RFC for a first-class callable syntax, which is intended as a simpler alternative to the partial function application (PFA) proposal:
https://wiki.php.net/rfc/first_class_callable_syntax See the Rationale section for details on how this relates to PFA. Over the past week, we've had a lot of discussions on how exactly PFA is supposed to work (most of them OTR), and while we seem to have a tentative consensus on the correct model to use (which does not match the current RFC), it's clear that this feature has turned out more complicated than originally anticipated. Joe (who provided the implementation for the PFA RFC) is also concerned about the implementation complexity that the final model would require. At least I personally was mainly interested in PFA because it provides a first-class callable syntax as a side-effect. This RFC goes back to providing *just* that. The syntax is forward-compatible with a future PFA proposal though. Regards, Nikita
