My grievance is so not with you @paulinpaloalto, who for years have set the bar for thorough exposition both syntactic and semantic. 
Here is an example of what I mean. NLP Assignment 4 Grading Problem - #13 by Mubsi
The learner actually writes It finally worked. Got full grades. thanks a ton. can you tell me what was the issue? Was the learner scored on submitted code they didn’t write? Was it a temporary system issue? An unhandled edge case in the grader code? Only Mubsi knows. A missed opportunity for digital exhaust that would benefit the broader community of learners and mentors alike.
