I'm not sure I follow exactly what you mean, could you give a small example
of the interface and usage? It sounds like you are referring to something
along the lines of C# properties though I don't immediately see what you are
using dynamic casting for or what exactly this provides as a benefit over
get/set methods. Thanks.
