PHP __callStatic&无效的方法名称字符

Quick question regarding __callStatic() in PHP;

class Test{
    public static function __callStatic($method, $arguments){
        echo $method . PHP_EOL;
    }
    public function __call($method, $arguments){
        echo $method . PHP_EOL;
    }
}

$test = new Test();

$test->foo();
$test->{'hello-world'}();

Test::bar();
Test::{'goodbye-universe'}();

Expected output:

foo
hello-world
bar
goodbye-universe

Actual output:

foo
hello-world
bar
PHP Parse error:  syntax error, unexpected '{', expecting T_STRING or T_VARIABLE or '$' in - on line 18

Is this syntax not permissible, nor functionality achievable with __callStatic()?

Note: Trying to get away with no temporary variables. The following will work:

$goodbyeUniverse = 'goodbye-universe';
Test::$goodbyeUniverse();

But I'm trying to avoid that.
