http://www.gopherjs.org/play/#/OAURs5D1wS ```go package main import ( "fmt" ) type Foo string func (foo *Foo) Hello() { fmt.Printf("Hello, I am %s\n", *foo) } var theFoo = Foo("the global foo") func main() { theFoo.Hello() } ``` This panics with the message `panic: theFoo$24ptr is not defined`. This works fine with the original Go: https://play.golang.org/p/h8I6Uqc0SP
