* Write stub as valid PHP This works probably because it is not parsed by PHP but by something more tolerant, but let's make it more valid (the final access type in the signature is not valid) PHP anyway, that will raise fewer eyebrows. * Document actual return type Seeca006e54e3/Zend/zend_exceptions.stub.php (L8)* Mark all methods from Throwable as mutation free Exception is the only possible class implementation of Throwable, and all of its methods except __toString() are final. Seeca006e54e3/Zend/zend_exceptions.stub.php (L3-L25)Closes #3170
