      public static <T> T newProxy(com.google.common.reflect.TypeToken<T> enclosingType, com.google.common.base.Function<Invocation,Object> invocationFunction)
      Returns a proxy instance that implements enclosingType by dispatching method invocations to invocationFunction. The class loader of enclosingType will be used to define the proxy class.

      Usage example: 

       httpAdapter = new Function<Invocation, Result>() {
    public Result apply(Invocation in) {
       try {
          HttpRequest request = parseRequest(in);
          HttpResponse response = invoke(request);
          return Result.success(parseJson(response));
       } catch (Exception e) {
          return Result.failure(e);
       }
    }
 };
 
 client = FunctionalReflection.newProxy(Client.class, httpAdapter);
      Parameters:
      invocationFunction - returns a result or a top-level exception, or result
      Throws:
      IllegalArgumentException - if enclosingType does not specify the type of a Java interface
