Hi, changes to isSuperTypeOf need to be verified in TypeCombinatorTest::testUnion and testIntersect. So please add some cases to the data providers there. You need to test expectations with different types that should hit different branches in that method. Thank you. |

Hi, thank you for such a quick reply :)
Are the tests that I've added sufficient, or do I need to add some for the branches that I didn't touch too? |

Please test intersection with 'array' too - should be NeverType.

Fixing the test for phpstan/phpstan#6697 would make it 'array'&class-string<T (function foo(), parameter)> instead of never, because we would need to assume that 'array' may be name of a class PHPStan doesn't know about. What should I do about that?

This broke the test for phpstan/phpstan#6697. Not sure what to do here. Fixing phpstan/phpstan#10076 requires assuming that constant string is not a class-string unless PHPStan knows about that class, while phpstan/phpstan#6697 relies on the assumption that constant string may be a name of a class that PHPStan doesn't know about. |

@ondrejmirtes Friendly ping, I need your decision here. |
Fixes phpstan/phpstan#10076.
