This is not the case, because you still have an instance "Quoted
String". Then you can write:
$(myLang [|..|])
Where myLang :: String -> Q Exp
Ah, you're right. I find an instance Quoted String a little
confusing and would probably write $(myLang "..") instead. Hmm, this
is more complicated if the string contains line breaks and [|..|]
would be an alternative string literal syntax where line breaks don't
need to be escaped.
