Missing rector to downgrade Closure::fromCallable (PHP 7.1)

[bobab12]

Feature Request

There should be a rector rule to be able to downgrade Closure::fromCallable (PHP 7.1), see https://www.php.net/manual/en/closure.fromcallable.php.

Diff

-\Closure::fromCallable('strtolower');
+$callable = 'strtolower';
+function () use ($callable) {
+    return $callable(...func_get_args());
+};

Hi, we don't plan to add such rule at the moment, as our main focus is improving DX and bug-fixes on upgrade. See https://getrector.org/blog/rector-for-php56-native

Would you like to contribute it?
