The point of short closure is to be one instruction only, plus you can already have the body of a short closure on multiple lines.

Regular closure can do multiple lines and instruction already.

To me this is a tiny syntactic sugar that is really unecessary.

Thanks to readonly properties, I started relying more and more on properties alone. However, I actually often find the need for more fine-grained control over input and output, but adding methods feels so heavy-weight. Property hooks feels like the perfect solution for some of my use cases.

In combination with Asymmetric visibility this will allow to replace all getters and setters with trivial properties and occasional hooks.

Short closures were meant to be that - short. If you need multiple lines, just create a function (it can even be a closure). Or just use a standard anonymous function instead of a short closure. It will also create confusion with having access to variables outside the short closure scope while letting it look like a normal function.

With First-class callable syntax available since 8.1, it would now be possible to write it as below, which is much better then string names of functions:

$result = "Hello World"
    |> htmlentities(...)
    |> str_split(...)
    |> fn($x) => array_map(strtoupper(...), $x)
    |> fn($x) => array_filter($x, fn($v) => $v != 'O');
