-multiple analyzers. It is based on the multichecker package

-	    atomic       check for common mistakes using the sync/atomic package
-	    ...

-	unusedresult: check for unused results of calls to some functions

-	  -unusedresult.stringmethods value
-	        comma-separated list of names of methods of type func() string whose results must be used

-	Some functions like fmt.Errorf return a result and have no side effects,
