Review enumeration string reporting

[dupdob]

Enumerations are not properly displayed. Enumerations that are part of another enumerations are reported as included in the root enumerations.

Expected Behavior

var a = new int[]{1,2};
var root = new List<object> ();
root.AddRange(a);
recursive.Add(a);

Should be reported as : {1,2, {1,2}}

Current Behavior

var a = new int[]{1,2};
var root = new List<object> ();
root.AddRange(a);
recursive.Add(a);

Is reported as : {1,2, 1,2}!
