Code inspection: Redundant braces in collection initializer

This inspection reports braces around a collection initializer element when the element contains only a single non-assignment value. In that case, the extra braces are unnecessary and make the initializer harder to read.

                using System.Collections;
                class C
                {
                    object Create()
                    {
                        return new ArrayList { 1, { 2 } };
                    }
                }
            

                using System.Collections;
                class C
                {
                    object Create()
                    {
                        return new ArrayList { 1, 2 };
                    }
                }
            

This inspection does not report elements where the braces are required, such as multi-argument Add(...) calls.
