Yeah, I see, but there are cases, when my hand is inadvertently aiming to mark a post as satisfactory explanation 
A couple of recent examples:
-
one. In that topic I did not ask to “correct” my code, I only interested why compiler did not do what I expected. And the linked answer was the explanation.
-
two. For me this topic better fits into Explain category and the linked post is clear explanation too, “ping ponging between Sema and Codegen”.
And besides nobody forbids adding posts with some additional details after an issue was solved or a matter was explained.
