Q:

New prefab comment / delete recommendation reason for LQP queue

I am proposing a new pre-selectable reason to "recommend deletion" that comes with a comment:

Answers to non-trivial problems that contain code without any further explanation are unlikely to be of use for future visitors. Please add an explanation of your code to let your answer have lasting utility.

I'm running across these a lot. It gets a little annoying to have to comment every time. 

A:

I really don't see a need to add this.  You can always use the Auto Review Comments userscript to leave your own comments.  I currently have one for answers that need more of an explanation:

While this code snippet may solve the problem, including an explanation really helps to improve the quality of your post. Remember that you are answering the question for readers in the future, and those people might not understand why you have suggested this code or how it works.

This way you can customize what you want to say and you can add others without having to ask another feature request.
In addition you should not use recommend delete on a code only answer as it is an answer and not very low quality.  After I drop my comment I click looks okay.  You could skip if you do not like saying it looks okay but you should not recommend to delete.

A:

I entirely disagree with this feature-request.  Code only answers aren't usually bad enough to warrant deletion.  In fact, they should not be flagged as VLQ in the first place.  Adding this option to the official list of canned review comments will lead to more people incorrectly deleting things that should only be downvoted.  
When I come across these code-only answers in a VLQ review, I leave a comment the way Nathan suggests and then I review the post as "Looks OK."  If it's particularly unintelligible code I also open the answer in a new tab to downvote it.  
For more suggestions on how to process VLQ answers, Undo's recommendations are a good reference.  Reviewers shouldn't be overly eager to delete stuff via the VLQ queue.  The community will handle the bad code-only answer via the roomba script by downvoting the bad code-only answers.
