json.Unmarshal doesn't work

[hajimehoshi]

I know reflect is broken now, but I'm reporting this just in case.

The below code works on the Playground, but doesn't work on my local machine.

package main

import (
    "encoding/json"
    "fmt"
    "reflect"
)

type Foo struct {
    A int
}

func main() {
    s := `{"A": 1}`
    fooType := reflect.TypeOf((*Foo)(nil)).Elem()
    foo := reflect.New(fooType).Interface() 
    fmt.Printf("%v\n", foo)
    if err := json.Unmarshal([]byte(s), &foo); err != nil {
        panic(err)
    }
    fmt.Printf("%v\n", foo)
}

Uncaught TypeError: undefined is not a function

On Go 1.2 or 1.3? 1.2 should not be broken.

[hajimehoshi]

1.2, but not sure because I've installed 1.3 once and installed 1.2 again...

[hajimehoshi]

On 1.3, All but fmt.Printf seem to be working on ToT. Thank you!

It could be that reinstalling 1.2 over 1.3 doesn't work well. Please feel free to close this ticket.

Anyway thank you for fixing encoding/json!

So everything that was functioning with 1.2 is now with 1.3?

[hajimehoshi]

AFAIK Yes.

Great!
