The specific member that is chosen for a given operation depends on the operation arguments. For example, if a member set represents an overloaded method then the arguments to Invoke(array<Object>[]()[]) are used to select the specific overload to be invoked. If the overload cannot be determined automatically from the arguments, the client should use the WithSignature(array<Type>[]()[]) method to obtain a restricted member set given the method signature of the specific overload to be used then calling Invoke(array<Object>[]()[]) on the resulting member set.
