What did you do?

I tried to declare a string variable using backquote syntax. The string value should include an escaped backquote as showing in the code snippet below:

func main() {
	fmt.Println(`hello\``)
}

What did you expect to see?

Output:

hello`

What did you see instead?

Output:

./prog.go:8:22: string not terminated
./prog.go:8:22: syntax error: unexpected literal `)
}
 in argument list; possibly missing comma or )

working as intended. raw strings literals are defined to have no escapes.
