Giving a warning where you have not used a variable is not a sledgehammer,
it's a light thing, that helps keep code tidy and once in a while helps avoid
bugs.
My point is it is not a light thing. It negatively and irritatingly impacts
normal coding practices. Adding in pragmas uglifies the code. More compiler
switches increases the cognitive load.
(I've seen many build scripts for C/C++ that include a long list of switches. I
ask the developer what those switches do, he often has no idea. He just copied
the list of switches from some other project.)
So it's a tradeoff. How much time do you save when it finds an actual bug, vs
how much time it costs you to futz around trying to suppress invalid warnings.
