@staabm this needs improvement for loop and apply which shoud be avoided to avoid too early match type, which there is also possibly other type, like this PR:

• [TypeDeclaration] Skip multi sprintf possibly falsy on AddParamStringTypeFromSprintfUseRector #7490

the loop should return null early, or just count() === 1 verify early to avoid "another type" definition.
