What it does: After the method is called, it checks whether there are any 
ref-arguements. If that's true, it marshalls the C++ arg-values to C#-values 
and copies them on the C# stack. It basically does the same as your approach, 
but it doesn't need to have any extra marshallers; it uses the existing ones.
I think the two approaches are rather equal in their simplicity.
