The Pipe Operator
The "pipe operator" |> allows you to chain multiple function calls in a more convenient way.
$result = "Hello World" |> 'htmlentities' |> 'str_split' |> fn($x) => array_map('strtoupper', $x) |> fn($x) => array_filter($x, fn($v) => $v != 'O');
This RFC was already declined, but we're sharing it here as another test RFC, and because it'd be interesting to learn people's opinion about it.
This is another RFC that focuses on the Developer Experience of PHP and gets shutdown by internals because of bikeshedding or lack of interest in doing things for the sake of improving DX. The syntax allows for clear and concise code and goes hand-in-hand with First-party callable and short arrow functions. There aren't many things that can be expressed in a syntax, but this one can replace entire PHP libraries (kind of similar to PHP Enum) and make the entire pipeline process in PHP fluid and readable.
"Very good idea, but it would be nice to avoid using strings in the function calls."
Doesn't this proposal conflict with the Hack-like pipe operator where you can choose which argument to pipe into, using $$? This is not necessarily a no-vote, just a listed concern. :)
Also, the examples should use str_split(...) syntax, not strings, IMO.

Interface Default Methods improves backwards compatibility when changing interfaces, but also add a way to have multi-inheritance in PHP.
Chain method on newly created objects without parentheses
This RFC proposes a way to have multi-line short closures — closures that don't need explicit use statements, but can still have multiple lines and a return statement.
