Can I create a new function using reflection in Go?

Question

I have an idea to use interfaces in Go to define RPC style interfaces. So for a given service, I might create an interface like this:

type MyService interface{
          


        

Answer 1

It appears that the reflect package will gain the ability to create new arbitrarily typed functions in Go 1.1: reflect.MakeFunc.

(the following added in response to @nemo)

Instead of an interface, one could create a struct type:

type MyService struct{
  Login func(username, password string) (sessionId int, err error)
  HelloWorld func(sessionId int) (hi string, err error)
}

autorpc.ImplementService(&MyService, MyServiceURL)
session, err := MyService.Login(username, password)
stringout, err := MyService.HelloWorld(session)
