What do you understand by "a little"?

Please look at the example from 
http://www.digitalmars.com/webnews/newsgroups.php?
art_group=digitalmars.D&article_id=73441 

Do you recognize how many warnings a lint tool might emit on that code?
Would you admit then, that a paranoic lint would be quite useless, even 
if it detects that the variable `p' should be accessed? Would you 
admit, that you yourself are unable to decide whether the presence of 
some access statements to `p' should suppress the warning?

My understanding of lint tools is, that they incorporate a collection 
of programming patterns together with a fuzzy recognition algorithm. If 
there are enough hits for a specific pattern, but it is still only 
partial implemented, then warnings are generated. Under this the 
primary question is: what is so special to the collection of 
programming patterns that they can be formalized into a lint tool but 
not be used as paradigms in the source language?
