First and foremost, well done and good post i stumbled on youre old post from 2010 👍 "http://haacked.com/archive/2010/08/05/copying-attributes.aspx/" and wanted to pitch in for an update for enums. To fix proper handlings of enum for a constructors replace: `var value = argument.Value;` with ``` object value; if (argument.ArgumentType.IsEnum) { value = Enum.ToObject(argument.ArgumentType, argument.Value); } else { value = argument.Value; } ```
