Method calls with out or ref in their signatures do not return the return value.

What steps will reproduce the problem?
1. Create a .NET assembly with a class having the following method:
    public bool TryGetValue(Tkey key, out TValue value)
2. Load assembly from Lua
3. execute ret, value = obj:TryGetValue("somekey")

What is the expected output? What do you see instead?
ret should be a boolean indicating success.
value should be the value if successful, nil otherwise.

Instead the result is: ret contains the value if successful, nil otherwise. 
value is always nil.

What version of the product are you using? On what operating system?
LuaInterfalce 2.0.3
