This isn't a direct answer, but a workaround. Using PHP >= 7. Defining an anonymous class with a named method and constructing the class and calling the method right away.

$var = (new class() { // Anonymous class
    function cool() { // Named method
        return 'neato';
    }
})->cool(); // Instantiate the anonymous class and call the named method
echo $var; // Echos neato to console.
