Suppose that you are in a situation that you must provide a comment or say something, but actually you don't know what you should say. Finally, you come up with something which strikes the lister as complex, leading to a lengthy questions and answers between you and that person.
Now, suppose you want to imply "It wasn't well thought of comment and let's stop this topic"
I just wanted to have said something.
Is that grammatically right? I see zero result for "just wanted to have said" or almost zero for "wanted to have said" which make feel insecure about this sentence.
