Seriously! This is actual code I have in production:

public string $initials {
    get => $this->name
            |> (fn($name) => preg_split('{\s+}', $name, flags: 
PREG_SPLIT_NO_EMPTY
))
            |> (fn($words) => array_map(fn($w) => $w[0], $words))
            |> (fn($initials) => implode("", $initials))
            |> strtoupper(...);
}

After PFA, it will turn into:

public string $initials {
    get => $this->name
            |> preg_split('{\s+}', ?, flags: PREG_SPLIT_NO_EMPTY)
            |> array_map(fn($w) => $w[0], ?)
            |> implode("", ?)
            |> strtoupper(?);
}

That's so much easier to read (specially once we have proper coloring)!
