Adding a phpdoc to declare returning values of constants complains about the string native return type

[stof]

Bug report

When using a native return type ?string combined with an annotation @phpstan-return UnaryOperator::*|null, phpstan complains about the string type

Code snippet that reproduces the problem

https://phpstan.org/r/0346e5da-af41-4055-92d4-09021e4f5b8f

Expected output

no error being reported.

Did PHPStan help you today? Did it make you happy in any way?

I consider a static analysis of the PHP code a must-have today, so it definitely helps.

Hi, the error is expected, just the error message needed adjusting. The expected error message is: Method Parser::unaryOperatorFor() never returns 'not' so it can be removed from the return typehint.

Fixed: phpstan/phpstan-src@838d1e4

Well, with the right error message, I can understand the error 😄
