We have to look at those notes again and again in order to find if something important is noted, hence please always try to avoid all notes unless the effect is really intended!

Consider the Note "No visible binding for global variable" We cannot know if your code intends to use such a global variable (which is undesirable in most cases), hence would let is pass if it seems to be sensible.

Another Note such as "empty section" or "partial argument match" can quickly be fixed, hence just do it and don't waste our time.
