defining generic return for a method/function in php with phpdocblock

Question

Is there a way to specify that a function will return an object of a specific type, where the type is the string of one of the parameters?

e.g.

/**
 * @return object<$class>
 */
public function create(string $class): object {
 ... some factory stuff
}

so that vscode or phpstorm will know that when I do

$myvar = X::create('MyClass');

$myvar will be of type MyClass and I'll have the proper intellisense/autocompletion for it?

Answer 1

This could work using templates like this:

/**
 * @template T of object
 * @psalm-param class-string<T> $a
 * @param class-string<T> $a
 * @return T
 */
function foo($a)
{
    return $a;
}

But I don't know whether VSCode already supports that. PhpStorm for example doesn't know how to handle the returned value properly
