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 

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