[RFC] Pipe Assignment Operator

Hi internals, I'd like to open discussion on my (first!) RFC for the pipe assignment operator (|>=): https://wiki.php.net/rfc/pipe_assignment_operator It adds a compound assignment form of the pipe operator, so that $x |>= callable is shorthand for $x = $x |> callable, with support for chaining. Implementation with tests is at: https://github.com/php/php-src/pull/22633 Looking forward to your feedback. Thanks! Caleb
