I agree that explicit-per-use ratification is my preferred approach
here.  I agree almost completely on the grounds of transparency.

Neil:  Is it possible for hlint to read comments?  As a random example:
do c <- hGetContents h {-# HLINT: ignore "This use is safe." #-}
   return c

It's entirely possible that using the # like that would cause GHC's
parser to choke, so view this as an illustrative example only :)

Perhaps, it should work more like haddock where you use | and ^ to
effectively point forward or backwards in the source at the usage.  I
like the idea of being able to have a "comment" inside the ignore
