You're not using it currently, it does= n't mean you don't  intend to use it later, you still want to verify t= hat it has the right value should there come a time when you want to use it= , right?

The debugger is likely= to reuse the storage for something else, due to the variable having no lif= etime, so it wouldn’t be able to show the value for very long. Anyway= , there’s no reason to suppress warnings in unfinished code. If you i= ntend to use something in the near future, you wouldn’t mark it [[unu= sed]] because the warning serves as a useful reminder.

You'd also like to make sure any docum= entation tools that use these names have a name to work with, etc= .. etc. etc.

Such documentation is ba= sed on interface declarations, not implementation.
