FWIW, other (significant) compiler project (QuickC-- [1]) used grading
system for the very same purpose based on three values [quality,
importance, urgency], with the descriptive levels. This might give an
overview what is wrong with the piece of the code or what would be
needed to make it better, how important the piece of code is, and how
urgent would be to improve it.
