   ref to: #61

   Should use either GO_FAILPOINTS="mypackagename/demoPanic=return(\"100\")" or GO_FAILPOINTS='mypackagename/demoPanic=return("100")'

   // add.go
   func add(ctx context.Context) string {
        failpoint.InjectContext(ctx, "failpoint-name1", func(value failpoint.Value) string {
            failpoint.Return(value.(string))
        })
   
        return "1"
    }
   // add_test.go
    func TestAdd(t *testing.T) {
        err := failpoint.Enable("golangtest/gofailpoint/failpoint-name1", "return('0.01')")
        if err != nil {
            log.Fatal(err)
        }
   failpoints := map[string]struct{}{
            "golangtest/gofailpoint/failpoint-name1": {},
        }
        ctx := failpoint.WithHook(context.Background(), func(ctx context.Context, fpname string) bool {
            _, found := failpoints[fpname]
            return found
        })
        log.Println(add(ctx))
    }

   when I execute my program, it truns out that:

   error on golangtest/gofailpoint/failpoint-name1: failpoint: failed to parse "return('0.01')" past ")"

   how come does not it support "return('0.01')" of this pattern?
