Would be good to have a test like:

[Fact]
public static void Test_CustomAttributeTypedArgument_ToString()
{
    var argument = new CustomAttributeTypedArgument(new [] { new CustomAttributeTypedArgument(0) });

    Assert.Equal("new CustomAttributeTypedArgument[1] { 0 }", argument.ToString());
}

after:

runtime/src/libraries/System.Runtime/tests/System/Reflection/CustomAttribute_Named_Typed_ArgumentTests.cs

Line 53 in 39ece73

}
