You don't have to generate PHP code for this to work:
$arr = is_string($func) ? explode("::", $func, 2) : $func;
$ref = (sizeof($arr) === 2) ?
new ReflectionMethod($arr[0], $arr[1])
: new ReflectionFunction($func);
$args = identifyArgumentsAndGetCtorArgs($ref);
if (sizeof($arr) === 2 && $arr[1] === '__construct') {
$rc = new ReflectionClass($arr[0]);
return $rc->newInstanceArgs($args);
} else {
return $ref->invokeArgs($args);
}
I haven't tested this and it might need some fine tuning, but isn't
really complicated. (Of course you can generate PHP code for this
trivially in order to avoid the small reflection overhead)

I think it is quite obscure and a hardly used feature. Language features
and syntax sugar things should be common things.
