There was a problem hiding this comment.
Closure in attribute should be tested as well.
Also probably a "fail" in class method and no function in global context.

This commit introduces support for the new `Closure::getCurrent()` method, available in PHP 8.5 (implemented in php/php-src#18167 ). A special function handler has been implemented to correctly analyze calls to this method. When used within a closure or arrow function, the analyzer now correctly infers the return type as the signature of the current closure. This enables precise type-checking for recursive anonymous functions. Additionally, the analyzer will now emit an `InvalidStaticMethodCall` error if `Closure::getCurrent()` is used outside of a valid closure context (e.g., in the global scope or within a regular method/function), aligning with PHP's runtime behavior. The internal PHP stubs have also been updated to include this new method. Signed-off-by: azjezz <azjezz@protonmail.com>
