[RFC][DISCUSSION] Strict Argument Count

Hi, internals I'm moving the "Strict Argument Count" RFC into discussion phase: RFC: https://wiki.php.net/rfc/strict_argcount PR: https://github.com/php/php-src/pull/1108 Many different opinions were collected during research phase and the RFC was updated with real BC break measurements and other important sections. So, before discussing: - Even if you already read the RFC in the past, read it again now. - Don't claim **possible** massive BC breaks before read the measurements already done. No matter how seasoned you are with PHP, real numbers matter most than assumptions. Your measurements are welcome too. - Try the patch. Really. - Consider reading the use case present on this post: goo.gl/3ykdIy - Keep discussion on topic and remember we are all trying to improve PHP in some way :) Thanks, Márcio
