Thx for working on it. The test case shows what I expected.

Cannot judge the implementation... not much AST experience on my end

Maybe its a different topic, but I would also add the following example (Same idea but with typed property)

Before

class InferFromPropertyType
 {
     private int $id;

     public function setId($id)
     {
         $this->id = $id;
     }
 }

After

class InferFromPropertyType
 {
     private int $id;

     public function setId(int $id)
     {
         $this->id = $id;
     }
 }

Thanks, any review and feedback helps me 👍 . I'm blinded by my own ego.

Good idea, I'll add new type inferer.
