Naturally there was more conversation. :-) But good conversation, so the RFC has been updated again. I recommend everyone look it over another time. Highlights: * Joe was able to figure out how to fold the extra partial logic into the Closure object. So the Partial and ReflectionPartial classes are gone; partial application gives you a closure object that looks like any other, but still manages to optimize away repeated partial application. * Some descriptions were improved. * Constructors already worked, with some caveats. Joe managed to remove those caveats, so they now work as you would expect them to. (See the RFC section for details.) * I included some references to other languages and how they handle partial application. Short version: This is the most robust and most fully featured version of any language I could find. Rock on, PHP! :-) * Nicolas, I went ahead and made a test for partial-application-DI-autowiring, just to see what it would look like. It looks like this: https://github.com/php/php-src/pull/6898/files#diff-218bb085c4cf4a35da35aa2d7a5cabd77f053d6f975340c2ef10de6f30dee503 Whether that's actually useful or not I don't know, but there it is. :-) Since there were some substantive changes, we're pushing the vote start off until the first half of next week, Monday/Tuesday timeframe.
