[RFC] Function pipe operator

Hello fine people of Internals! I've been commenting on other RFCs enough lately that I should probably put myself through the wringer, too. I therefore offer this RFC to add a function pipe operator, as seen in a number of other languages: https://wiki.php.net/rfc/pipe-operator-v2 A patch is available here: https://github.com/php/php-src/pull/5425 Although I have one or two bits of it that I could use feedback on. (Let me know over on GitHub.) It's deliberately a very small, lightweight, and targeted change. The Future Work section suggests possible additions for later, but this is as much as my meager skills can manage for the moment. My enormous thanks to Sammy K Powers and Levi Morrison for their copious hand-holding in my first foray into php-src. *dons flame retardant suit* -- Larry Garfield larry@garfieldtech.com
