It should come as no surprise that writers take an interest in punctuation. I have been told that the dying words of one famous 20th-century writer were, "I should have used fewer semicolons" - and although I have spent months fruitlessly trying to track down the chap responsible, I believe it none the less. If it turns out that no one actually did say this on their deathbed, I shall certainly save it up for my own.
