I think we have enough infrastructure in the analysis based warnings (I think the sufficiency of the infrastructure is demonstrated by the "may be used uninitialized" warnings). Such a warning would subsume these narrower "set but not used" type of warnings (though would require the analysis warning infrastructure).



- Compile time cost could be a problem.
- Do we need stronger dead store warning? Clang analyzer checks for dead stores, no?

I would rather have this on by default with -Wall, than something stronger off by default
