I have been looking for a new language to try, and I'm on Go now after trying D. I'm stuck on this bit of code:

code:

package main

import "fmt"
import "reflect"

type Master struct {}

func (master *Master) Execute(i int, j int) {
	fmt.Println("did something")
}

func Invoke(any interface{}, name string, args... interface{}) {

	inputs := make([]reflect.Value, len(args))
	for i, param := range args {
		inputs[i] = reflect.ValueOf(param)
		fmt.Println(param)
	}
	
	reflect.ValueOf(any).MethodByName(name).Call(inputs)
}

func main() {
	Invoke(Master{}, "Execute", 1, 2)
}

It panics like so:

code:

panic: reflect: call of reflect.Value.Call on zero Value

But I don't understand why. It seems to be building the list of inputs to pass to Call, so I don't understand why it thinks the inputs are a "zero Value" :raise:

Wow, nice catch. Thanks for that.

Another oddity: http://play.golang.org/p/BMtgxj-0Af

Unmarshaling any number always gives me a float64 :raise:

Is there a way to force encoding/decoding an integer? I'm reading the json encoder but not seeing it.
