That looks like the weakest part of the proposition because we already have two places where inline bodies are used: the mentioned arrow functions and property hooks


  public string $foo { get => 'dynamic value'; }

No sense in introducing a new syntax for basically just another case of inline function body.


// oneline
function handle(string $input): string = func1($input) |> func2(...) 
|>            func3(...) |> func4(...);


That looks like a callable assignment like you know

  $f = fn ($bar) => $this->bar + $bar;

  class Foo {

      private $bar;



      public function bar() = $f;

  }

that may confuse users, another argument for =>
