[go-nuts] Creating methods at runtime for a dynamically-generated client library

I want to create a client library which reads a list of functions from a
service and exposes those functions to the caller.

Is it possible to create methods during runtime? E.g.:

type Foo struct {}

func main() {

// Create new method Bar on Foo here at runtime

           reflect.MakeMethod("Foo", "Bar", func(){} )

f := Foo{}

f.Bar()

}


The other way I'm thinking of doing this is by static code generation.
  Looks like that's how Google is doing it<https://code.google.com/p/google-api-go-client/>,
so that's probably the way to go, right?
