Implementation of collection initializer syntax support for constructor #194 Managed to somehow close the original PR on accident during rebase operation pull 246, but all comments have now been resolved.

You can now write

var target = new Interpreter();
target.Reference(typeof(System.Collections.Generic.List<>));
var intList = target.Eval<System.Collections.Generic.List<int>>("new List<int>(){1, 2, 3, 4, 5}");
Assert.AreEqual(5, intList.Count);
for (int i = 0; i < intList.Count; ++i)
{
    Assert.AreEqual(i + 1, intList[i]);
}
or 
 target.Eval<System.Collections.Generic.List<string>>("new List<string>(){string.Empty}");

as well as implementations supporting multiple parameters in the Add method such as

new MyClassAdder(){{ 1, 2, 3, 4, 5},{\"6\" },7 }
and
new Dictionary<int, string>(){{1, \"1\"}, {2, \"2\"}, {3, \"3\"}, {4, \"4\"}, {5, \"5\"}}

Reference to method parameters is also supported like below

target.Eval<System.Collections.Generic.List<string>>("new List<string>(){StrProp = string.Empty}", new Parameter("StrProp", "0")) target.Eval<System.Collections.Generic.List<string>>("new List<string>(){StrValue()}", new Parameter("StrValue", new Func<string>(() => "Func")))
