I don't write `("blabla") on the off-chance that someone would want to replace it with `(,(concat `"bla" `"bla")). We don't quote self-quoting forms gratuitously, and we don't use quasiquote gratuitously: the latter only gets used when we indeed use an unquoting form inside. In short, we don't use constructs for the sake of using constructs. -- David Kastrup
