From a bug I recently reported:

http://play.golang.org/p/zPMdG-kJ4b

[Rob Pike]

not an improvement, just an expansion of the idea:

http://play.golang.org/p/3pNo5hZ0NT

I'm seriously confused. Why does the lexer have those symbols?

It's to make Kafka parseable as Go code.

Haha! Can't test it locally right now, but is it just in the Playground?

It's possible to run locally, but you will have to invoke the toolchain directly (instead of using "go run").

$ cat 3pNo5hZ0NT.go

notwithstanding package main

whereas import "fmt"

func main(thetruthofthematter) {

        if despiteallobjections 2 + 2 == 5 {

                panic("Goodbye, cruel world!")

        }

        fmt.Println(insofaras "Phew, still safe.")

}

$ go run 3pNo5hZ0NT.go

3pNo5hZ0NT.go:1:1: expected 'package', found 'IDENT' notwithstanding

$ go tool 6g 3pNo5hZ0NT.go && go tool 6l 3pNo5hZ0NT.6 && ./6.out

Phew, still safe.
